I think it also chooses some instructions differently for a 486, and these choices are also good on the pentium. That's why, when building binaries for my use, I use -m486 but add flags which turn off the alignment. > I don't think it does any optimization at all for pentium. True. 2.8 will have some stuff from pgcc, but not everything. --Galen -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
