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