Two possibilities. First: #ifdef __STDC__ This worked well for me back when I was worried about this issue. Second, and the solution I recommend these days, is to simply assume C89 or better. Nobody uses pre-C89 compilers any more, except for computer museums (which are not a serious platform for the GNU project), so there's no point to have you worrying about pre-C89 compilers any more. GDB, GCC, coreutils, tar, etc., etc., all assume C89 or better now, so you'd be in good company. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
