+# 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.

+# 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_OPENMP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro tries to find out how to compile programs that use OpenMP a
+# standard API and set of compiler directives for parallel programming
+# (see http://www-unix.mcs/)
+#
+# On success, it sets the OPENMP_CFLAGS/OPENMP_CXXFLAGS/OPENMP_F77FLAGS
+# output variable to the flag (e.g. -omp) used both to compile *and* link
+# OpenMP programs in the current language.
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well.
+#
+# If you want to compile everything with OpenMP, you should set:
+#
+# CFLAGS="$CFLAGS $OPENMP_CFLAGS"
+# #OR# CXXFLAGS="$CXXFLAGS $OPENMP_CXXFLAGS"
+# #OR# FFLAGS="$FFLAGS $OPENMP_FFLAGS"
+#
+# (depending on the selected language).
+#
+# The user can override the default choice by setting the corresponding
+# environment variable (e.g. OPENMP_CFLAGS).
+#
+# ACTION-IF-FOUND is a list of shell commands to run if an OpenMP flag 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_OPENMP.

+#
+# 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.

+## typically no way to rebuild the header). We avoid this by adding
+## dummy dependencies for each header file. Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'. On the theory
+## that the space means something, we add a space to the output as
+## well. hp depmode also adds that space, but also prefixes the VPATH
