Something like this?????

===================================================================RCS file: /usr/cvs/cm3/m3-sys/m3cc/gcc/gcc/m3cg/parse.c,vretrieving revision 1.41diff -r1.41 parse.c3066a3070>   tree atypes = NULL_TREE);3091c3095,3102<   TREE_TYPE (p) = build_function_type (return_type, NULL_TREE);--->   /* for NT386 __stdcall, we just need to declare the right number>   of parameters>   */>   if (--n_params== 0) {>     atypes = tree_cons (NULL_TREE, t_word, atypes);>   }>>   TREE_TYPE (p) = build_function_type (return_type, atypes);

haven't even compiled it yet..
