	Well, I bought the Greenhills C compiler for my 68k box and found an
interesting bug.  It created code that would core dump on any switch statement
that had 3 cases ( or was it four? ).  The solution was to use the -O flag.
However, I did not trust the compiler for non-optimized, let alone optimized,
work.  Anyway, I have not bothered to reinstall it when I switched disks.

	Who knows, maybe their cross compilers are better.  I don't know
what platform you are compiling for, but the gnu compiler generates some
of the tightest 68k  code I have seen and may have a cross compilation
capability.  It is also free.

	Anyway, good luck.
