Boy, John are you in luck!

Everyone else is worried about ELF's PE's and I don't know what else (I still
would like to know though).  Your COFF object should have an .o extension.
Just add it to the list of sources being fed to gcc. -	Make sure you have
your functions prototyped as extern. -	Assure your functions will be
declared as Global in your other source. -  Function names have to look like
what the compiler expects, so a prefixed underscore must be assured. -	If
you are compiling as c++ you must also assure name mangling will be
accomodated.  The easiest way is usually to prototype the function(s) as
extern "C" to eliminate this need.

BTW if you are linking with NASM there is a good tutorial on this.
