computer-go: gmp question

[Chris Fant <fantius@xxxxxxxxxxxx>]

I'm ready to add serial gmp to my program.  I'm glad gmp exists, but I 
don't care about its internals.  What is the easiest way for me to do 
this?  I know about the cgf dll and the cgfcomm c++ file and cgf.c, all of 
which I got found at the same place 
(http://www.hiroshima-pu.ac.jp/~sasaki/cgf/files/).  My program is ansi C 
on Windows 2000.  Which one should I use?
