See autoconf/lib/freeze.mk:check-forbidden-patterns and autoconf/lib/*/Makefile.am:forbidden_patterns Since the workaround is so easy in this case (./configure GREP=grep), and I'd call IRIX an, umm, rather less important target, but most of all since Autoconf has documented for a long time now that AC_PROG_GREP checks for multiple -e, I would vote for keeping it that way. Hope that helps. Cheers, Ralf
