The Lattice C large model is actually huge (unless you use an option). The PC-AT large model (which has yet to work properly for any non trivial program I've tried) is not. I have seen a huge model Microsoft compiler when is even more buggy than the large model. It did however successfully compile and run the sieve program with results about the same as Lattice huge model.

Note that these results don't quite match those shown in Intel's ads. That's because 32 bit programs are being compared with 16 bit programs. There are 16 bit 68000 compilers that beat these figures, just as 8086 compilers do better when they don't try to emulate a real processor. -:) -- Chuck Forsberg WA7KGX ..!tektronix!reed!omen!caf Omen Technology Inc 17505-V NW Sauvie IS RD Portland OR 97231 Voice: 503-621-3406 Modem: 503-621-3746 (Hit CR's for speed detect)
