vmMain needs to return a pointer because of GAME_CLIENT_CONNECT in
code/game/g_main.c.

vmMain ends up as vm->entryPoint. It's return value is used as
intptr_t in VM_Call (vm.c, line 743). I really can't see what can go
wrong there. Especially since you only changed the ui, game and
cgame still use intptr_t.

The change affects the dll interface only, does that mean
interpreter works?
