-# SYNOPSIS
-#
-# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
-#
-# DESCRIPTION
-#
-# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
-# added in between.
-#
-# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
-# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
-# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
-# FLAG.
-#
-# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

-#
-# DESCRIPTION
-#
-# Try to find a compiler option that enables most reasonable warnings.
-#
-# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
-# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
-#
-# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
-# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
-# Intel compilers. For a given compiler, the Fortran flags are much more
-# experimental than their C equivalents.
-#
-# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
-# - $2 add-value-if-not-found : nothing
-# - $3 action-if-found : add value to shellvariable
-# - $4 action-if-not-found : nothing
-#
-# NOTE: These macros depend on AX_APPEND_FLAG.

-# SYNOPSIS
-#
-# 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:
-#
-# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
