-#
-# 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.

-#
-# DESCRIPTION
-#
-#   Check whether the given FLAG works with the current language's
-#   preprocessor/compiler/linker, or whether they give 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 us thus made
-#   with the following flags: "CFLAGS EXTRA-FLAGS FLAG".  EXTRA-FLAGS can
-#   for example be used to force the compiler to issue an error when a bad
-#   flag is given.
-#
-#   AX_APPEND_FLAG appends the FLAG to the FLAG-VARIABLE shell variable or
-#   the current language's flags if not specified.  FLAG is not added to
-#   FLAG-VARIABLE if it is already in the shell variable.
-#
-#   AX_APPEND_COMPILE_FLAGS checks for each FLAG1, FLAG2, etc. using
-#   AX_CHECK_COMPILE_FLAG and if the check is successful the flag is added
-#   to the appropriate FLAGS variable with AX_APPEND_FLAG.  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 CXXFLAGS 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.

-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the C++11
-#   standard; if necessary, add switches to CXXFLAGS 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.

-#
-# SYNOPSIS
-#
-#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads. It
-#   sets the PTHREAD_LIBS output variable to the threads library and linker
-#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
-#   flags that are needed. (The user can also force certain compiler
-#   flags/libs to be tested by setting these environment variables.)
-#
-#   Also sets PTHREAD_CC to any special C compiler that is needed for
-#   multi-threaded programs (defaults to the value of CC otherwise). (This
-#   is necessary on AIX to use the special cc_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these flags,
-#   but also link it with them as well. e.g. you should link with
-#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#
-#   If you are only building threads programs, you may wish to use these
-#   variables in your default LIBS, CFLAGS, and CC:
-#
-#     LIBS="$PTHREAD_LIBS $LIBS"
-#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#     CC="$PTHREAD_CC"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
-#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
-#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
-#   PTHREAD_CFLAGS.
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
-#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
-#   is not found. If ACTION-IF-FOUND is not specified, the default action
-#   will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or if
-#   you have any other suggestions or comments. This macro was based on work
-#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
-#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
-#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
-#   grateful for the helpful feedback of numerous users.

-#   Provides a test for the compiler support of thread local storage (TLS)
-#   extensions. Defines TLS if it is found. Currently knows about GCC/ICC
-#   and MSVC. I think SunPro uses the same as GCC, and Borland apparently
