+   Many packages have scripts meant for developers instead of ordinary

+installed, or they may access the network, which has privacy
+implications.  If the ‘bootstrap’ shell script exists, it attempts to
+build the ‘configure’ shell script and related files, possibly using
+developer tools or the network.  Because the output of ‘bootstrap’ is
+system-independent, it is normally run by a package developer so that

+   See “Defining Variables” for more details.
 
 Compiling For Multiple Architectures
 ====================================
 
    You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU 'make'.  'cd' to the
-directory where you want the object files and executables to go and run
-the 'configure' script.  'configure' automatically checks for the source
-code in the directory that 'configure' is in and in '..'.  This is known
-as a "VPATH" build.
-
-   With a non-GNU 'make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use 'make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple '-arch' options to the
-compiler but only a single '-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results

+
+   Some platforms, notably macOS, support “fat” or “universal” binaries,
+where a single binary can execute on different architectures.  On these
+platforms you can configure and compile just once, with options specific
+to that platform.
 
 Installation Names
 ==================
 
-   By default, 'make install' installs the package's commands under
-'/usr/local/bin', include files under '/usr/local/include', etc.  You
-can specify an installation prefix other than '/usr/local' by giving

-   Some packages pay attention to '--enable-FEATURE' options to

-They may also pay attention to '--with-PACKAGE' options, where PACKAGE
-is something like 'gnu-as' or 'x' (for the X Window System).  The
-'README' should mention any '--enable-' and '--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, 'configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the 'configure' options '--x-includes=DIR' and
-'--x-libraries=DIR' to specify their locations.
+   Some packages pay attention to ‘--enable-FEATURE’ and
+‘--disable-FEATURE’ options to ‘configure’, where FEATURE indicates an
+optional part of the package.  They may also pay attention to
+‘--with-PACKAGE’ and ‘--without-PACKAGE’ options, where PACKAGE is
+something like ‘gnu-ld’.  ‘./configure --help’ should mention the
+‘--enable-...’ and ‘--with-...’ options that the package recognizes.
 
    Some packages offer the ability to configure how verbose the
-execution of 'make' will be.  For these packages, running './configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with 'make V=1'; while running './configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with 'make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
-is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX 'make' updates targets which have the same time stamps as their
-prerequisites, which makes it generally unusable when shipped generated
-files such as 'configure' are involved.  Use GNU 'make' instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
-workaround.  If GNU CC is not installed, it is therefore recommended to
-try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
-in your 'PATH', put it _after_ '/usr/bin'.
-
-   On Haiku, software installed for all users goes in '/boot/common',
-not '/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
+execution of ‘make’ will be.  For these packages, running ‘./configure
+--enable-silent-rules’ sets the default to minimal output, which can be
+overridden with ‘make V=1’; while running ‘./configure
+--disable-silent-rules’ sets the default to verbose, which can be
+overridden with ‘make V=0’.
+
+Specifying a System Type
+========================
+
+   By default ‘configure’ builds for the current system.  To create
+binaries that can run on a different system type, specify a
+‘--host=TYPE’ option along with compiler variables that specify how to
+generate object code for TYPE.  For example, to create binaries intended
+to run on a 64-bit ARM processor:
+
+     ./configure --host=aarch64-linux-gnu \
+        CC=aarch64-linux-gnu-gcc \
+        CXX=aarch64-linux-gnu-g++
+
+If done on a machine that can execute these binaries (e.g., via
+‘qemu-aarch64’, ‘$QEMU_LD_PREFIX’, and Linux’s ‘binfmt_misc’
+capability), the build behaves like a native build.  Otherwise it is a
+cross-build: ‘configure’ will make cross-compilation guesses instead of
+running test programs, and ‘make check’ will not work.
+
+   A system type can either be a short name like ‘mingw64’, or a
+canonical name like ‘x86_64-pc-linux-gnu’.  Canonical names have the
+form CPU-COMPANY-SYSTEM where SYSTEM is either OS or KERNEL-OS.  To
+canonicalize and validate a system type, you can run the command
+‘config.sub’, which is often squirreled away in a subdirectory like
+‘build-aux’.  For example:
+
+     $ build-aux/config.sub arm64-linux
+     aarch64-unknown-linux-gnu
+     $ build-aux/config.sub riscv-lnx
+     Invalid configuration 'riscv-lnx': OS 'lnx' not recognized
+
+You can look at the ‘config.sub’ file to see which types are recognized.
+If the file is absent, this package does not need the system type.
+
+   If ‘configure’ fails with the diagnostic “cannot guess build type”.
+‘config.sub’ did not recognize your system’s type.  In this case, first
+fetch the newest versions of these files from the GNU config package
+(https://savannah.gnu.org/projects/config).  If that fixes things,
+please report it to the maintainers of the package containing
+‘configure’.  Otherwise, you can try the configure option ‘--build=TYPE’
+where TYPE comes close to your system type; also, please report the
+problem to <config-patches@gnu.org>.
 
-Specifying the System Type
-==========================
-
-   There may be some features 'configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, 'configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-'--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as 'sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file 'config.sub' for the possible values of each field.  If
-'config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.

 Sharing Defaults
 ================

-default values for variables like 'CC', 'cache_file', and 'prefix'.
-'configure' looks for 'PREFIX/share/config.site' if it exists, then
-'PREFIX/etc/config.site' if it exists.  Or, you can set the
-'CONFIG_SITE' environment variable to the location of the site script.

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, ext|noext, mandatory|optional)
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11', '14', '17', '20', or
+#   '23' for the respective C++ standard version.
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for no added switch, and then for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

+   See “Defining Variables” for more details.
 
 Compiling For Multiple Architectures
 ====================================
 
    You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU 'make'.  'cd' to the
-directory where you want the object files and executables to go and run
-the 'configure' script.  'configure' automatically checks for the source
-code in the directory that 'configure' is in and in '..'.  This is known
-as a "VPATH" build.
-
-   With a non-GNU 'make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use 'make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple '-arch' options to the
-compiler but only a single '-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"

-   This is not guaranteed to produce working output in all cases, you

+
+   Some platforms, notably macOS, support “fat” or “universal” binaries,
+where a single binary can execute on different architectures.  On these
+platforms you can configure and compile just once, with options specific
+to that platform.
 
 Installation Names
 ==================
 
-   By default, 'make install' installs the package's commands under
-'/usr/local/bin', include files under '/usr/local/include', etc.  You
-can specify an installation prefix other than '/usr/local' by giving
-'configure' the option '--prefix=PREFIX', where PREFIX must be an

-   Some packages pay attention to '--enable-FEATURE' options to

-They may also pay attention to '--with-PACKAGE' options, where PACKAGE
-is something like 'gnu-as' or 'x' (for the X Window System).  The
-'README' should mention any '--enable-' and '--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, 'configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the 'configure' options '--x-includes=DIR' and
-'--x-libraries=DIR' to specify their locations.
+   Some packages pay attention to ‘--enable-FEATURE’ and
+‘--disable-FEATURE’ options to ‘configure’, where FEATURE indicates an
+optional part of the package.  They may also pay attention to
+‘--with-PACKAGE’ and ‘--without-PACKAGE’ options, where PACKAGE is
+something like ‘gnu-ld’.  ‘./configure --help’ should mention the
+‘--enable-...’ and ‘--with-...’ options that the package recognizes.
 
    Some packages offer the ability to configure how verbose the
-execution of 'make' will be.  For these packages, running './configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with 'make V=1'; while running './configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with 'make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
-is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX 'make' updates targets which have the same time stamps as their
-prerequisites, which makes it generally unusable when shipped generated
-files such as 'configure' are involved.  Use GNU 'make' instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
-workaround.  If GNU CC is not installed, it is therefore recommended to
-try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
-in your 'PATH', put it _after_ '/usr/bin'.
-
-   On Haiku, software installed for all users goes in '/boot/common',
-not '/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
+execution of ‘make’ will be.  For these packages, running ‘./configure
+--enable-silent-rules’ sets the default to minimal output, which can be
+overridden with ‘make V=1’; while running ‘./configure
+--disable-silent-rules’ sets the default to verbose, which can be
+overridden with ‘make V=0’.
+
+Specifying a System Type
+========================
+
+   By default ‘configure’ builds for the current system.  To create
+binaries that can run on a different system type, specify a
+‘--host=TYPE’ option along with compiler variables that specify how to
+generate object code for TYPE.  For example, to create binaries intended
+to run on a 64-bit ARM processor:
+
+     ./configure --host=aarch64-linux-gnu \
+        CC=aarch64-linux-gnu-gcc \
+        CXX=aarch64-linux-gnu-g++
+
+If done on a machine that can execute these binaries (e.g., via
+‘qemu-aarch64’, ‘$QEMU_LD_PREFIX’, and Linux’s ‘binfmt_misc’
+capability), the build behaves like a native build.  Otherwise it is a
+cross-build: ‘configure’ will make cross-compilation guesses instead of
+running test programs, and ‘make check’ will not work.
+
+   A system type can either be a short name like ‘mingw64’, or a
+canonical name like ‘x86_64-pc-linux-gnu’.  Canonical names have the
+form CPU-COMPANY-SYSTEM where SYSTEM is either OS or KERNEL-OS.  To
+canonicalize and validate a system type, you can run the command
+‘config.sub’, which is often squirreled away in a subdirectory like
+‘build-aux’.  For example:
+
+     $ build-aux/config.sub arm64-linux
+     aarch64-unknown-linux-gnu
+     $ build-aux/config.sub riscv-lnx
+     Invalid configuration 'riscv-lnx': OS 'lnx' not recognized
+
+You can look at the ‘config.sub’ file to see which types are recognized.
+If the file is absent, this package does not need the system type.
+
+   If ‘configure’ fails with the diagnostic “cannot guess build type”.
+‘config.sub’ did not recognize your system’s type.  In this case, first
+fetch the newest versions of these files from the GNU config package
+(https://savannah.gnu.org/projects/config).  If that fixes things,
+please report it to the maintainers of the package containing
+‘configure’.  Otherwise, you can try the configure option ‘--build=TYPE’
+where TYPE comes close to your system type; also, please report the
+problem to <config-patches@gnu.org>.
 
-Specifying the System Type
-==========================
-
-   There may be some features 'configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, 'configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the

-type, such as 'sun4', or a canonical name which has the form:

 Sharing Defaults
 ================

-'configure' looks for 'PREFIX/share/config.site' if it exists, then

-'CONFIG_SITE' environment variable to the location of the site script.

-instructions specific to this package.  Some packages provide this
-'INSTALL' file but do not implement all of the features documented

+     make
+     make install
+
+should configure, build, and install this package.  The first line,
+which bootstraps, is intended for developers; when building from
+distribution tarballs it does nothing and can be skipped.

+   The following more-detailed instructions are generic; see the
+‘README’ file for instructions specific to this package.  Some packages
+provide this ‘INSTALL’ file but do not implement all of the features
+documented below.  The lack of an optional feature in a given package is
+not necessarily a bug.  More recommendations for GNU packages can be
+found in the GNU Coding Standards.
+
+   Many packages have scripts meant for developers instead of ordinary
+builders, as they may use developer tools that are less commonly
+installed, or they may access the network, which has privacy
+implications.  If the ‘bootstrap’ shell script exists, it attempts to
+build the ‘configure’ shell script and related files, possibly using
+developer tools or the network.  Because the output of ‘bootstrap’ is
+system-independent, it is normally run by a package developer so that
+its output can be put into the distribution tarball and ordinary
+builders and users need not run ‘bootstrap’.  Some packages have
+commands like ‘./autopull.sh’ and ‘./autogen.sh’ that you can run
+instead of ‘./bootstrap’, for more fine-grained control over
+bootstrapping.

 results of its tests to speed up reconfiguring.  Caching is disabled by

-you want to change it or regenerate 'configure' using a newer version of

+   The ‘autoconf’ program generates ‘configure’ from the file

+editing ‘configure’ directly.
 
    The simplest way to compile this package is:

+     developer tools and network access to bootstrap, and the network

 Compiling For Multiple Architectures
 ====================================
 
    You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU 'make'.  'cd' to the
-directory where you want the object files and executables to go and run
-the 'configure' script.  'configure' automatically checks for the source
-code in the directory that 'configure' is in and in '..'.  This is known
-as a "VPATH" build.
-
-   With a non-GNU 'make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use 'make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple '-arch' options to the
-compiler but only a single '-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results

+
+   Some platforms, notably macOS, support “fat” or “universal” binaries,
+where a single binary can execute on different architectures.  On these
+platforms you can configure and compile just once, with options specific
+to that platform.
 
 Installation Names
 ==================
 
-   By default, 'make install' installs the package's commands under
-'/usr/local/bin', include files under '/usr/local/include', etc.  You
-can specify an installation prefix other than '/usr/local' by giving
-'configure' the option '--prefix=PREFIX', where PREFIX must be an

-   Some packages pay attention to '--enable-FEATURE' options to

-They may also pay attention to '--with-PACKAGE' options, where PACKAGE
-is something like 'gnu-as' or 'x' (for the X Window System).  The
-'README' should mention any '--enable-' and '--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, 'configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the 'configure' options '--x-includes=DIR' and
-'--x-libraries=DIR' to specify their locations.
+   Some packages pay attention to ‘--enable-FEATURE’ and
+‘--disable-FEATURE’ options to ‘configure’, where FEATURE indicates an
+optional part of the package.  They may also pay attention to
+‘--with-PACKAGE’ and ‘--without-PACKAGE’ options, where PACKAGE is
+something like ‘gnu-ld’.  ‘./configure --help’ should mention the
+‘--enable-...’ and ‘--with-...’ options that the package recognizes.
 
    Some packages offer the ability to configure how verbose the
-execution of 'make' will be.  For these packages, running './configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with 'make V=1'; while running './configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with 'make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
-is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX 'make' updates targets which have the same time stamps as their
-prerequisites, which makes it generally unusable when shipped generated
-files such as 'configure' are involved.  Use GNU 'make' instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
-workaround.  If GNU CC is not installed, it is therefore recommended to
-try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
-in your 'PATH', put it _after_ '/usr/bin'.
-
-   On Haiku, software installed for all users goes in '/boot/common',
-not '/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
+execution of ‘make’ will be.  For these packages, running ‘./configure
+--enable-silent-rules’ sets the default to minimal output, which can be
+overridden with ‘make V=1’; while running ‘./configure
+--disable-silent-rules’ sets the default to verbose, which can be
+overridden with ‘make V=0’.
+
+Specifying a System Type
+========================
+
+   By default ‘configure’ builds for the current system.  To create
+binaries that can run on a different system type, specify a
+‘--host=TYPE’ option along with compiler variables that specify how to
+generate object code for TYPE.  For example, to create binaries intended
+to run on a 64-bit ARM processor:
+
+     ./configure --host=aarch64-linux-gnu \
+        CC=aarch64-linux-gnu-gcc \
+        CXX=aarch64-linux-gnu-g++
+
+If done on a machine that can execute these binaries (e.g., via
+‘qemu-aarch64’, ‘$QEMU_LD_PREFIX’, and Linux’s ‘binfmt_misc’
+capability), the build behaves like a native build.  Otherwise it is a
+cross-build: ‘configure’ will make cross-compilation guesses instead of
+running test programs, and ‘make check’ will not work.
+
+   A system type can either be a short name like ‘mingw64’, or a
+canonical name like ‘x86_64-pc-linux-gnu’.  Canonical names have the
+form CPU-COMPANY-SYSTEM where SYSTEM is either OS or KERNEL-OS.  To
+canonicalize and validate a system type, you can run the command
+‘config.sub’, which is often squirreled away in a subdirectory like
+‘build-aux’.  For example:
+
+     $ build-aux/config.sub arm64-linux
+     aarch64-unknown-linux-gnu
+     $ build-aux/config.sub riscv-lnx
+     Invalid configuration 'riscv-lnx': OS 'lnx' not recognized
+
+You can look at the ‘config.sub’ file to see which types are recognized.
+If the file is absent, this package does not need the system type.
+
+   If ‘configure’ fails with the diagnostic “cannot guess build type”.
+‘config.sub’ did not recognize your system’s type.  In this case, first
+fetch the newest versions of these files from the GNU config package
+(https://savannah.gnu.org/projects/config).  If that fixes things,
+please report it to the maintainers of the package containing
+‘configure’.  Otherwise, you can try the configure option ‘--build=TYPE’
+where TYPE comes close to your system type; also, please report the
+problem to <config-patches@gnu.org>.
 
-Specifying the System Type
-==========================
-
-   There may be some features 'configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, 'configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-'--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as 'sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file 'config.sub' for the possible values of each field.  If
-'config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option '--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with '--host=TYPE'.
+   For more details about configuring system types, see the Autoconf
+documentation.
 
 Sharing Defaults
 ================
 
-   If you want to set default values for 'configure' scripts to share,
-you can create a site shell script called 'config.site' that gives
-default values for variables like 'CC', 'cache_file', and 'prefix'.
-'configure' looks for 'PREFIX/share/config.site' if it exists, then
-'PREFIX/etc/config.site' if it exists.  Or, you can set the
-'CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all 'configure' scripts look for a site script.

 ==================
 
    Variables not defined in a site shell script can be set in the

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, ext|noext, mandatory|optional)
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11', '14', '17', '20', or
+#   '23' for the respective C++ standard version.
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for no added switch, and then for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

+#  ii) func_quote_arg_unquoted_result
+#      has all characters that are still active within double
+#      quotes backslashified.  Available only if 'unquoted' is specified.
+#
+# Available modes:
+# ----------------
+# 'eval' (default)
+#       - escape shell special characters
+# 'expand'
+#       - the same as 'eval';  but do not quote variable references
+# 'pretty'
+#       - request aesthetic output, i.e. '"a b"' instead of 'a\ b'.  This might
+#         be used later in func_quote to get output like: 'echo "a b"' instead
+#         of 'echo a\ b'.  This is slower than default on some shells.
+# 'unquoted'
+#       - produce also $func_quote_arg_unquoted_result which does not contain
+#         wrapping double-quotes.
+#
+# Examples for 'func_quote_arg pretty,unquoted string':
