# SYNOPSIS
#
# AX_CFLAGS_GCC_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
#
# DESCRIPTION
#
# AX_CFLAGS_GCC_OPTION(-fvomit-frame) would show a message as like
# "checking CFLAGS for gcc -fvomit-frame ... yes" and adds the optionflag
# to CFLAGS if it is understood. You can override the shellvar-default of
# CFLAGS of course. The order of arguments stems from the explicit macros
# like AX_CFLAGS_WARN_ALL.
#
# The cousin AX_CXXFLAGS_GCC_OPTION would check for an option to add to
# CXXFLAGS - and it uses the autoconf setup for C++ instead of C (since it
# is possible to use different compilers for C and C++).
#
# The macro is a lot simpler than any special AX_CFLAGS_* macro (or
# ac_cxx_rtti.m4 macro) but allows to check for arbitrary options.
# However, if you use this macro in a few places, it would be great if you
# would make up a new function-macro and submit it to the ac-archive.
#
# - $1 option-to-check-for : required ("-option" as non-value)
# - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case)
# - $3 action-if-found : add value to shellvariable
# - $4 action-if-not-found : nothing
#
# Note: in earlier versions, $1-$2 were swapped. We try to detect the
# situation and accept a $2=~/-/ as being the old option-to-check-for.
#
# There are other variants that emerged from the original macro variant
# which did just test an option to be possibly added. However, some
# compilers accept an option silently, or possibly for just another option
# that was not intended. Therefore, we have to do a generic test for a
# compiler family. For gcc we check "-pedantic" being accepted which is
# also understood by compilers who just want to be compatible with gcc
# even when not being made from gcc sources.
#
# See also: AX_CFLAGS_SUN_OPTION, AX_CFLAGS_HPUX_OPTION,
# AX_CFLAGS_AIX_OPTION, and AX_CFLAGS_IRIX_OPTION.
