+# 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

+# noclone

+# 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.
