There aren't any 486 or 586 optimizations that cause GCC code to fail
on 386 machines. Search for "-m386" in the GCC Info pages:
Control whether or not code is optimized for a 486 instead of an
386. Code generated for an 486 will run on a 386 and vice versa.
There are some other options that will speed up performance on 586
machines, but I'm not as keen on those.
