Some ideas:
The problem does seem to come from incompatible definitions of 
CreateDialog, in both gtkgame.h and windows.h.

How come it did compile before adding multiprocessing support, ie 
before adding pthreads and sockets? Something must have changed in the 
way you're compiling/linking? Was windows.h included in previous 
compiles of dice.c? Where does windows.h get included from? 
winsocket.h? Maybe you can include gtkgame.h before 
winsocket.h/windows.h and tweak windows.h so it doesn't declare 
CreateDialog() if _GTKGAME_H_ is already defined? Or maybe we should 
rename gnubg's CreateDialog() to something like GTK_CreateDialog()?

Does the problem appear only in dice.c? Or does it also show up in 
other .c files?

Maybe I should try to merge the current gnubg version into the multi 
branch...?
