+# SYNOPSIS
+#
+#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   For every FLAG1, FLAG2 it is checked whether the compiler works with the
+#   flag.  If it does, the flag is added FLAGS-VARIABLE
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  During the check the flag is always added to the
+#   current language's flags.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: This macro depends on the AX_APPEND_FLAG and
+#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
+#   AX_APPEND_LINK_FLAGS.

+#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
+#
+# DESCRIPTION
+#
+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
+#   added in between.
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
+#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
+#   FLAG.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

+# SYNOPSIS
+#
+#   AX_CFLAGS_GCC_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
+#
+# DESCRIPTION
+#
+#   AX_CFLAGS_GCC_OPTION(-fvomit-frame) would show a message as like
+#   "checking CFLAGS for gcc -fvomit-frame ... yes" and adds the
+#   optionflag to CFLAGS if it is understood. You can override the
+#   shellvar-default of CFLAGS of course. The order of arguments stems
+#   from the explicit macros like AX_CFLAGS_WARN_ALL.
+#
+#   The cousin AX_CXXFLAGS_GCC_OPTION would check for an option to add
+#   to CXXFLAGS - and it uses the autoconf setup for C++ instead of C
+#   (since it is possible to use different compilers for C and C++).
+#
+#   The macro is a lot simpler than any special AX_CFLAGS_* macro (or
+#   ac_cxx_rtti.m4 macro) but allows to check for arbitrary options.
+#   However, if you use this macro in a few places, it would be great
+#   if you would make up a new function-macro and submit it to the
+#   ac-archive.
+#
+#     - $1 option-to-check-for : required ("-option" as non-value)
+#     - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case)
+#     - $3 action-if-found : add value to shellvariable
+#     - $4 action-if-not-found : nothing
+#
+#   note: in earlier versions, $1-$2 were swapped. We try to detect the
+#   situation and accept a $2=~/-/ as being the old
+#   option-to-check-for.
+#
+#   also: there are other variants that emerged from the original macro
+#   variant which did just test an option to be possibly added.
+#   However, some compilers accept an option silently, or possibly for
+#   just another option that was not intended. Therefore, we have to do
+#   a generic test for a compiler family. For gcc we check "-pedantic"
+#   being accepted which is also understood by compilers who just want
+#   to be compatible with gcc even when not being made from gcc
+#   sources.
+#
+#   see also:

+# SYNOPSIS
+#
+#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   or gives an error.  (Warnings, however, are ignored)
+#
+#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+#   success/failure.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+#   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' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   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 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.

+#
+#   AX_CXX_COMPILE_STDCXX_11([ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the C++11
+#   standard; if necessary, add switches to CXX and CXXCPP to enable
+#   support.
+#
+#   This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
+#   macro with the version set to C++11.  The two optional arguments are
+#   forwarded literally as the second and third argument respectively.
+#   Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
+#   more information.  If you want to use this macro, you also need to
+#   download the ax_cxx_compile_stdcxx.m4 file.

+#   AX_LD_CHECK_FLAG(FLAG-TO-CHECK,[PROLOGUE],[BODY],[ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tests if the C++ compiler supports the flag FLAG-TO-CHECK. If
+#   successfull execute ACTION-IF-SUCCESS otherwise ACTION-IF-FAILURE.
+#   PROLOGUE and BODY are optional and should be used as in AC_LANG_PROGRAM
+#   macro.
+#
+#   Example:
+#
+#     AX_LD_CHECK_FLAG([-Wl,-L/usr/lib],[],[],[
+#       ...
+#     ],[
+#       ...
+#     ])
+#
+#   This code is inspired from KDE_CHECK_COMPILER_FLAG macro. Thanks to
+#   Bogdan Drozdowski <bogdandr@op.pl> for testing and bug fixes.

+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+#   Here's an example:
+#
+#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

+#   Provides a test for the compiler support of thread local storage (TLS)
