+# 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.

+# 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
+# fallthrough
+# flatten
+# format
+# format_arg
+# gnu_inline
+# hot
+# ifunc
+# leaf
+# malloc
+# noclone
+# noinline
+# nonnull
+# noreturn
+# nothrow
+# optimize
+# pure
+# sentinel
+# sentinel_position
+# unused
+# used
+# visibility
+# warning
+# warn_unused_result
+# weak
+# weakref
+#
+# Unsupported 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.

+# 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:

+# Generate automatic documentation using Doxygen. Works in concert with the
+# aminclude.m4 file and a compatible doxygen configuration file. Defines the
+# following public macros:
+#
+# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
+# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
+# for generating a separate .chi file by the .chm file, and 'MAN', 'RTF',
+# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
+# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
+# paper size.
+#
+# By default, HTML, PDF and PS documentation is generated as this seems to be
+# the most popular and portable combination. MAN pages created by Doxygen are
+# usually problematic, though by picking an appropriate subset and doing some
+# massaging they might be better than nothing. CHM and RTF are specific for MS
+# (note that you can't generate both HTML and CHM at the same time). The XML is
+# rather useless unless you apply specialized post-processing to it.
+#
+# The macro mainly controls the default state of the feature. The use can
+# override the default by specifying --enable or --disable. The macros ensure
+# that contradictory flags are not given (e.g., --enable-doxygen-html and
+# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
+# Finally, each feature will be automatically disabled (with a warning) if the
+# required programs are missing.
+#
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
+# the following parameters: a one-word name for the project for use as a
+# filename base etc., an optional configuration file name (the default is
+# 'Doxyfile', the same as Doxygen's default), and an optional output directory
