# ===========================================================================

# ===========================================================================
#
# 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.
