Perhaps you could save CFLAGS, append -Werror, run your test, and then restore the previous CFLAGS. That might work. Of course, your test would break with any other compiler. Maybe a case check: 'if gcc, use -Werror, if compilerX use <Whatever>, etc.' not a great solution... :| anyone else have better ideas? -tom _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
