Result: about 2 % slower than the standard GCC (2.7.something back then) even when running on a pentium. So then i tried compiling with -m386 and that turned out to be faster than -m486 on both a 486 and a pentium. (again only a few % difference). Now i use the standard gcc compiler with the Linux distribution, with flags -O2 -fomit-frame-pointer -m386 I guess i must code in a different style to everyone else. I've also found that GCC is no worse than Digital Unix C on an Alpha, for my programs. Gcc was 10% faster on one program, about the same for two others, including the chess program. Nearly everyone else who has used it says gcc is hopeless on Alphas.
