I'm very much with Ralf C. about _not_ using compiler versions for checks, only as a last resort. But _if_ I were to need the last resort, for example as the ACTION-IF-CROSS-COMPILE action, I would check GCC's version with the preprocessor macros __GNUC__, __GNUC_MINOR__, __GNUC_PATCHLEVEL__ Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
