Is it to my advantage to compile with -m486? Some benchmarks run 10% faster if compiled with -m486 and run on 486 or P5 processors. Almost all programs will run slower if compiled with -m486 and run on 386 processors. -- Paul Vixie La Honda, CA "Illegitimi non carborundum." <paul@vix.com> pacbell!vixie!paul (dont let the bastards grind you down)
