The autoconf manual indicates that AC_WARNING is obsolete and that one should use m4_warn instead. But, yes, given how I was calling things, I missed that the message was being printed at autoconf time. As it turns out, AC_WARNING doesn't produce anything in a configure script. For the simple thing I was trying to do, it appears that AC_MSG_NOTICE is the macro to use. Thanks again for your assistance. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
