+# 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_CHECK_GNU_MAKE()
+#
+# DESCRIPTION
+#
+# This macro searches for a GNU version of make. If a match is found:
+#
+# * The makefile variable `ifGNUmake' is set to the empty string, otherwise
+# it is set to "#". This is useful for including a special features in a
+# Makefile, which cannot be handled by other versions of make.
+# * The variable `_cv_gnu_make_command` is set to the command to invoke
+# GNU make if it exists, the empty string otherwise.
+# * The variable `ax_cv_gnu_make_command` is set to the command to invoke
+# GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
+# * If GNU Make is found, its version is extracted from the output of
+# `make --version` as the last field of a record of space-separated
+# columns and saved into the variable `ax_check_gnu_make_version`.
+#
+# Here is an example of its use:
+#
+# Makefile.in might contain:
+#
+# # A failsafe way of putting a dependency rule into a makefile
+# $(DEPEND):
+# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+# @ifGNUmake@ include $(DEPEND)
+# @ifGNUmake@ endif
+#
+# Then configure.in would normally contain:
+#
+# AX_CHECK_GNU_MAKE()
+# AC_OUTPUT(Makefile)
+#
+# Then perhaps to cause gnu make to override any other make, we could do
+# something like this (note that GNU make always looks for GNUmakefile
+# first):
+#
+# if ! test x$_cv_gnu_make_command = x ; then
+# mv Makefile GNUmakefile
+# echo .DEFAULT: > Makefile ;
+# echo \ $_cv_gnu_make_command \$@ >> Makefile;
+# fi
+#
+# Then, if any (well almost any) other make is called, and GNU make also
+# exists, then the other make wraps the GNU make.

+# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+# Check whether the given FLAG works with the linker 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 linker's default flags
+# when the check is done. The check is thus made with the flags: "LDFLAGS
+# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
+# issue an error when a bad flag is given.
+#
+# INPUT gives an alternative input source to AC_LINK_IFELSE.
+#
+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

+# SYNOPSIS
+#
+# AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LDFLAGS which should be
+# included in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LDFLAGS variables of
+# every build target (program or library) which should be built with code
+# coverage support. Also defines CODE_COVERAGE_RULES which should be
+# substituted in your Makefile; and $enable_code_coverage which can be
+# used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
+# and substituted, and corresponds to the value of the
+# --enable-code-coverage option, which defaults to being disabled.
+#
+# Test also for gcov program and create GCOV variable that could be
+# substituted.
+#
+# Note that all optimisation flags in CFLAGS must be disabled when code
+# coverage is enabled.
+#
+# Usage example:
+#
+# configure.ac:
+#
+# AX_CODE_COVERAGE
+#
+# Makefile.am:
+#
+# @CODE_COVERAGE_RULES@
+# my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ...
+# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+# This results in a "check-code-coverage" rule being added to any
+# Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
+# has been configured with --enable-code-coverage). Running `make
+# check-code-coverage` in that directory will run the module's test suite
+# (`make check`) and build a code coverage report detailing the code which
+# was touched, then print the URI for the report.
+#
+# This code was derived from Makefile.decl in GLib, originally licenced
+# under LGPLv2.1+.

+#
+# AX_CONFIGURE_ARGS
+#
+# DESCRIPTION
+#
+# Helper macro for AX_ENABLE_BUILDDIR.
+#
+# The traditional way of starting a subdir-configure is running the script
+# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
+# to rely on eval'ing $ac_configure_args however some old autoconf
+# versions do not provide that. To ensure maximum portability of autoconf
+# extension macros this helper can be AC_REQUIRE'd so that
+# $ac_configure_args will alsways be present.
+#
+# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
+# spoiled now and must be replaced by "eval + exit $?".
+#
+# Example:
+#
+# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
+# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
+# eval $SHELL $ac_configure_args || exit $?
+# ...])

+# SYNOPSIS
+#
+# AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
+#
+# DESCRIPTION
+#
+# If the current configure was run within the srcdir then we move all
+# configure-files into a subdir and let the configure steps continue
+# there. We provide an option --disable-builddir to suppress the move into
+# a separate builddir.
+#
+# Defaults:
+#
+# $1 = $host (overridden with $HOST)
+# $2 = Makefile.mk
+# $3 = -all
+#
+# This macro must be called before AM_INIT_AUTOMAKE. It creates a default
+# toplevel srcdir Makefile from the information found in the created
+# toplevel builddir Makefile. It just copies the variables and
+# rule-targets, each extended with a default rule-execution that recurses
+# into the build directory of the current "HOST". You can override the
+# auto-dection through `config.guess` and build-time of course, as in
+#
+# make HOST=i386-mingw-cross
+#
+# which can of course set at configure time as well using
+#
+# configure --host=i386-mingw-cross
+#
+# After the default has been created, additional rules can be appended
+# that will not just recurse into the subdirectories and only ever exist
+# in the srcdir toplevel makefile - these parts are read from the $2 =
+# Makefile.mk file
+#
+# The automatic rules are usually scanning the toplevel Makefile for lines
+# like '#### $host |$builddir' to recognize the place where to recurse
+# into. Usually, the last one is the only one used. However, almost all
+# targets have an additional "*-all" rule which makes the script to
+# recurse into _all_ variants of the current HOST (!!) setting. The "-all"
+# suffix can be overriden for the macro as well.
+#
+# a special rule is only given for things like "dist" that will copy the
+# tarball from the builddir to the sourcedir (or $(PUB)) for reason of
+# convenience.

+# SYNOPSIS
+#
+# AX_EXTEND_SRCDIR
+#
+# DESCRIPTION
+#
+# The AX_EXTEND_SRCDIR macro extends $srcdir by one path component.
+#
+# As an example, when working in /home/michael/i3-4.12/build and calling
+# ../configure, your $srcdir is "..". After calling AX_EXTEND_SRCDIR,
+# $srcdir will be set to "../../i3-4.12".
+#
+# The result of extending $srcdir is that filenames (e.g. in the output of
+# the "backtrace" gdb command) will include one more path component of the
+# absolute source path. The additional path component makes it easy for
+# users to recognize which files belong to the PACKAGE, and -- provided a
+# dist tarball was unpacked -- which version of PACKAGE was used.
+#
+# As an example, in "backtrace", you will see:
+#
+# #0 main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187
+#
+# instead of:
+#
+# #0 main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187
+#
+# In case your code uses the __FILE__ preprocessor directive to refer to
+# the filename of the current source file (e.g. in debug messages), using
+# the extended path might be undesirable. For this purpose,
+# AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS,
+# which can be added to AM_CPPFLAGS in Makefile.am in order to define the
+# preprocessor directive STRIPPED__FILE__. As an example, when compiling
+# the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to
+# "main.c".
+#
+# There are some caveats: When $srcdir is "." (i.e. when ./configure was
+# called instead of ../configure in a separate build directory),
+# AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will
+# not be achieved because of the way automake specifies file paths:
+# automake defines COMPILE to use "`test -f '$source' || echo
+# '\$(srcdir)/'`$source" in order to prefer files in the current directory
+# over specifying $srcdir explicitly.
+#
+# The AX_EXTEND_SRCDIR author is not aware of any way to influence this
+# automake behavior. Patches very welcome.
+#
+# To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding
+# the following code to configure.ac:
+#
+# AX_ENABLE_BUILDDIR
+# dnl ...
+# AX_EXTEND_SRCDIR
+#
+# Then also add this bit to Makefile.am (if you wish to use
+# STRIPPED__FILE__ in your code):
+#
+# AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@

+# Offers users to enable one or more sanitizers (see
+# https://github.com/google/sanitizers) with the corresponding
+# --enable-<sanitizer>-sanitizer option.
+#
+# SANITIZERS is a whitespace-separated list of sanitizers to offer via
+# --enable-<sanitizer>-sanitizer options, e.g. "address memory" for the
+# address sanitizer and the memory sanitizer. If SANITIZERS is not specified,
+# all known sanitizers to AX_SANITIZERS will be offered, which at the time of
+# writing are "address memory undefined".
+# NOTE that SANITIZERS is expanded at autoconf time, not at configure time,
+# i.e. you cannot use shell variables in SANITIZERS.
+#
+# ENABLED-BY-DEFAULT is a whitespace-separated list of sanitizers which
+# should be enabled by default, e.g. "memory undefined". Note that not all
+# sanitizers can be combined, e.g. memory sanitizer cannot be enabled when
+# address sanitizer is already enabled.
+# Set ENABLED-BY-DEFAULT to a single whitespace in order to disable all
+# sanitizers by default.
+# ENABLED-BY-DEFAULT is expanded at configure time, so you can use shell
+# variables.
+#
+# ACTION-SUCCESS allows to specify shell commands to execute on success, i.e.
+# when one of the sanitizers was successfully enabled. This is a good place
+# to call AC_DEFINE for any precompiler constants you might need to make your
+# code play nice with sanitizers.
+#
+# The variable ax_enabled_sanitizers contains a whitespace-separated list of
+# all enabled sanitizers, so that you can print them at the end of configure,
+# if you wish.
+#
+# The additional --enable-sanitizers option allows users to enable/disable
+# all sanitizers, effectively overriding ENABLED-BY-DEFAULT.
+#
