I don't know about the alpha, but for the x86 line, it doesn't do any harm. It does some - minimal - amount of good. gcc has bugs when you start enabling optimizations, and you may see that kind of thing on the alpha processor for processor-specific flags. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
