Note that -O2 implies -fstrict-aliasing. I'm not sure how recent "sufficiently recent" is. I know that GCC 4.0 improved on the GCC 3.x compilers quite a bit for this kind of analysis, but I also know that GCC 4.1 and 4.2 both contained further improvements. I'm currently using Fedora 10, which ships with GCC 4.3.2. In 2 weeks, I'll be running Fedora 11, which ships with GCC 4.4.0. -- Jerry James http://www.jamezone.org/ _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
