While -mcpu keeps compatability at the expense of some optimazations iirc. The other thing that may make a difference is the CHOST setting, PPro and better use "i686-pc-linux-gnu" even athlon. Pentium Classics, K6s, MIIs and the like use "i586-pc-linux-gnu" i am not 100% certain _what_ the difference is. But "i686-..." will not work on "i586-..." so i am guessing it is some sort of optimization. -- Munir Nassar Systems Administrator RedConcepts.NET _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
