On Solaris, -m32 is a default for the SunPRO compilers. Both -m32 and -m64 worked quite good for me. They are very careful to provide both 32 and 64 bit versions of all libraries with the system, and system includes a lot of things, like X/Gnome etc. I never did used -m32 on Linux (knocking on the wood). >=20 > : Merged x86 tree is ortoghonal to this feature. >=20 > Yes, that's a much better way of saying what I was trying to say. >=20 > Warner --O7hm+SMpb/lu0d4d Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkuL9ocACgkQC3+MBN1Mb4glJACfUbsb8Isz0Ykcr9nbKmRV1/pU U8YAoLiVoWvj0oNBlfj9EvevLby8cFEE =/ywn -----END PGP SIGNATURE----- --O7hm+SMpb/lu0d4d--
