-#
-# 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.

-#
-# SYNOPSIS
-#
-# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
-#
-# DESCRIPTION
-#
-# Check for the presence of an --enable-debug option to configure, with
-# the specified default value used when the option is not present. Return
-# the value in the variable $ax_enable_debug.
-#
-# Specifying 'yes' adds '-g -O0' to the compilation flags for all
-# languages. Specifying 'info' adds '-g' to the compilation flags.
-# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
-# the linking flags. Otherwise, nothing is added.
-#
-# Define the variables listed in the second argument if debug is enabled,
-# defaulting to no variables. Defines the variables listed in the third
-# argument if debug is disabled, defaulting to NDEBUG. All lists of
-# variables should be space-separated.
-#
-# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
-# Should be invoked prior to any AC_PROG_* compiler checks.
-#
-# IS-RELEASE can be used to change the default to 'no' when making a
-# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
-# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
-# macro, there is no need to pass this parameter.

-# SYNOPSIS
-#
-# AX_GCC_FUNC_ATTRIBUTE(ATTRIBUTE)
-#
-# DESCRIPTION
-#
-# This macro checks if the compiler supports one of GCC's function
-# attributes; many other compilers also provide function attributes with
-# the same syntax. Compiler warnings are used to detect supported
-# attributes as unsupported ones are ignored by default so quieting
-# warnings when using this macro will yield false positives.
-#
-# The ATTRIBUTE parameter holds the name of the attribute to be checked.
-#
-# If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
-#
-# The macro caches its result in the ax_cv_have_func_attribute_<attribute>
-# variable.
-#
-# The macro currently supports the following function attributes:
-#
-# alias
-# aligned
-# alloc_size
-# always_inline
-# artificial
-# cold
-# const
-# constructor
-# constructor_priority for constructor attribute with priority
-# deprecated
-# destructor
-# dllexport
-# dllimport
-# error
-# externally_visible
-# flatten
-# format
-# format_arg
-# gnu_inline
-# hot
-# ifunc
-# leaf
-# malloc
-# noclone
-# noinline
-# nonnull
-# noreturn
-# nothrow
-# optimize
-# pure
-# unused
-# used
-# visibility
-# warning
-# warn_unused_result
-# weak
-# weakref
-#
-# Unsuppored function attributes will be tested with a prototype returning
-# an int and not accepting any arguments and the result of the check might
-# be wrong or meaningless so use with care.

-# 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.
