-#
-# DESCRIPTION
-#
-# For every FLAG1, FLAG2 it is checked whether the compiler works with the

-#
-# 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

-# SYNOPSIS
-#
-# AX_COMPILER_FLAGS([CFLAGS-VARIABLE], [LDFLAGS-VARIABLE], [IS-RELEASE], [EXTRA-BASE-CFLAGS], [EXTRA-YES-CFLAGS], [UNUSED], [UNUSED], [UNUSED], [EXTRA-BASE-LDFLAGS], [EXTRA-YES-LDFLAGS], [UNUSED], [UNUSED], [UNUSED])
-#
-# DESCRIPTION
-#
-# Check for the presence of an --enable-compile-warnings option to
-# configure, defaulting to "error" in normal operation, or "yes" if
-# IS-RELEASE is equal to "yes". Return the value in the variable
-# $ax_enable_compile_warnings.
-#
-# Depending on the value of --enable-compile-warnings, different compiler
-# warnings are checked to see if they work with the current compiler and,
-# if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This
-# allows a consistent set of baseline compiler warnings to be used across
-# a code base, irrespective of any warnings enabled locally by individual
-# developers. By standardising the warnings used by all developers of a
-# project, the project can commit to a zero-warnings policy, using -Werror
-# to prevent compilation if new warnings are introduced. This makes
-# catching bugs which are flagged by warnings a lot easier.
-#
-# By providing a consistent --enable-compile-warnings argument across all
-# projects using this macro, continuous integration systems can easily be
-# configured the same for all projects. Automated systems or build
-# systems aimed at beginners may want to pass the --disable-Werror
-# argument to unconditionally prevent warnings being fatal.
-#
-# --enable-compile-warnings can take the values:
-#
-# * no: Base compiler warnings only; not even -Wall.
-# * yes: The above, plus a broad range of useful warnings.
-# * error: The above, plus -Werror so that all warnings are fatal.
-# Use --disable-Werror to override this and disable fatal
-# warnings.
-#
-# The set of base and enabled flags can be augmented using the
-# EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and
-# appended to the output variable if --enable-compile-warnings is not
-# "no". Flags should not be disabled using these arguments, as the entire
-# point of AX_COMPILER_FLAGS is to enforce a consistent set of useful
-# compiler warnings on code, using warnings which have been chosen for low
-# false positive rates. If a compiler emits false positives for a
-# warning, a #pragma should be used in the code to disable the warning
-# locally. See:
-#
-# https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas
-#
-# The EXTRA-* variables should only be used to supply extra warning flags,
-# and not general purpose compiler flags, as they are controlled by
-# configure options such as --disable-Werror.
-#
-# IS-RELEASE can be used to disable -Werror when making a release, which
-# is useful for those hairy moments when you just want to get the release
-# done as quickly as possible. Set it to "yes" to disable -Werror. 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. For
-# example:
-#
-# AX_IS_RELEASE([git-directory])
-# AX_COMPILER_FLAGS()
-#
-# CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults
-# to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must
-# be manually added to the CFLAGS and LDFLAGS variables for each target in
-# the code base.
-#
-# If C++ language support is enabled with AC_PROG_CXX, which must occur
-# before this macro in configure.ac, warning flags for the C++ compiler
-# are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the
-# CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can
-# be used to augment the base and enabled flags.
-#
-# Warning flags for g-ir-scanner (from GObject Introspection) are
-# AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added
-# to the SCANNERFLAGS variable for each GIR target in the code base. If
-# extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR
-# macro must be invoked manually.
-#
-# AX_COMPILER_FLAGS may add support for other tools in future, in addition
-# to the compiler and linker. No extra EXTRA-* variables will be added
-# for those tools, and all extra support will still use the single
-# --enable-compile-warnings configure option. For finer grained control
-# over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS,
-# AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools.
-#
-# The UNUSED variables date from a previous version of this macro, and are
-# automatically appended to the preceding non-UNUSED variable. They should
-# be left empty in new uses of the macro.

-# DESCRIPTION
-#
-# Add warning flags for the g-ir-scanner (from GObject Introspection) to
