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. dnl dnl see also: dnl dnl AX_CFLAGS_SUN_OPTION AX_CFLAGS_HPUX_OPTION dnl AX_CFLAGS_AIX_OPTION AX_CFLAGS_IRIX_OPTION dnl dnl @category C dnl @author Guido Draheim dnl @version 2003-11-04 dnl @license GPLWithACException AC_DEFUN([AX_CFLAGS_GCC_OPTION_OLD], [dnl AS_VAR_PUSHDEF([FLAGS],[CFLAGS])dnl AS_VAR_PUSHDEF([VAR],[ac_cv_cflags_gcc_option_$2])dnl AC_CACHE_CHECK([m4_ifval($1,$1,FLAGS) for gcc m4_ifval($2,$2,-option)], VAR,[VAR="no, unknown" AC_LANG_SAVE AC_LANG_C ac_save_[]FLAGS="$[]FLAGS" for ac_arg dnl in "-pedantic % m4_ifval($2,$2,-option)" dnl GCC # do FLAGS="$ac_save_[]FLAGS "`echo $ac_arg | sed -e 's,%%.*,,' -e 's,%,,'` AC_TRY_COMPILE([],[return 0;], [VAR=`echo $ac_arg | sed -e 's,.*% *,,'` ;
