I've narrowed the problem down to the -msse2 that is in the version of Makefile.inc1 that I have. I notice that this flag was removed in Makefile.inc1 v1.499.2.18. Some manual experimenting with the CFLAGS implied by that Makefile suggests that the problem goes away with the newer Makefile.inc1. I will upgrade world and retry. --=20 Peter Jeremy --LQksG6bCIzRHxTLp Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGNC4Q/opHv/APuIcRAsGmAKCQO6+YlDHNo43OHKPN9dvQNLFKTwCgsNlp xpcOjKfGyZWOwbm6kJDIc/E= =79L8 -----END PGP SIGNATURE----- --LQksG6bCIzRHxTLp--
