coff.h has raw information about the format (but with little documentation). 
There was also some info in _PC Magazine_ a while back (I can't remember which
issue) because Windoze 32-bit executables are COFFs with small stubs prepended.
I doubt that there's a whole lot more info, though--_PC Mag_ said that they had
so much trouble getting it that they had to consult the GCC source! :-)
