+# 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.

+#
+# SYNOPSIS
+#
+# AX_CFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+# AX_CXXFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+# AX_FCFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+#
+# DESCRIPTION
+#
+# Specify compiler options that enable most reasonable warnings. For the
+# GNU Compiler Collection (GCC), for example, it will be "-Wall". The
+# result is added to shellvar, one of CFLAGS, CXXFLAGS or FCFLAGS if the
+# first parameter is not specified.
+#
+# Each of these macros accepts the following optional arguments:
+#
+# - $1 - shellvar
+# shell variable to use (CFLAGS, CXXFLAGS or FCFLAGS if not
+# specified, depending on macro)
+#
+# - $2 - default
+# value to use for flags if compiler vendor cannot be determined (by
+# default, "")
+#
+# - $3 - action-if-found
+# action to take if the compiler vendor has been successfully
+# determined (by default, add the appropriate compiler flags to
+# shellvar)
+#
+# - $4 - action-if-not-found
+# action to take if the compiler vendor has not been determined or
+# is unknown (by default, add the default flags, or "" if not
+# specified, to shellvar)
+#
+# These macros use AX_COMPILER_VENDOR to determine which flags should be
+# returned for a given compiler. Not all compilers currently have flags
+# defined for them; patches are welcome. If need be, compiler flags may
+# be made language-dependent: use a construct like the following:
+#
+# [vendor_name], [m4_if(_AC_LANG_PREFIX,[C], VAR="--relevant-c-flags",dnl
+# m4_if(_AC_LANG_PREFIX,[CXX], VAR="--relevant-c++-flags",dnl
+# m4_if(_AC_LANG_PREFIX,[FC], VAR="--relevant-fortran-flags",dnl
+# VAR="$2"; FOUND="no")))],
+#
+# Note: These macros also depend on AX_PREPEND_FLAG.

+# AX_COMPILER_VENDOR
+#
+# DESCRIPTION
+#
+# Determine the vendor of the C, C++ or Fortran compiler. The vendor is
+# returned in the cache variable $ax_cv_c_compiler_vendor for C,
+# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for
+# (modern) Fortran. The value is one of "intel", "ibm", "pathscale",

+# (GCC), "sun" (Oracle Developer Studio), "hp", "dec", "borland",
+# "comeau", "kai", "lcc", "sgi", "microsoft", "metrowerks", "watcom",
+# "tcc" (Tiny CC) or "unknown" (if the compiler cannot be determined).
+#
+# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT
+# with an appropriate preprocessor-enabled extension. For example:
+#
+# AC_LANG_PUSH([Fortran])
+# AC_PROG_FC
+# AC_FC_PP_SRCEXT([F])

+# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have

+# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found

+# It's like AC_REQUIRE except it doesn't expand the required macro.
