In fact, it doesn't compile. :-/

You've added a call to IsRectEmpty() to macdrv.h, which doesn't #include winuser.h.  That alone only causes an implicit declaration warning.  However, clipboard.c includes winuser.h after macdrv.h, which causes an error about the conflict between the real and implicit declarations.

You can move the include of winuser.h from all of the modules to macdrv.h, but make sure to #define OEMRESOURCE before it, as required by mouse.c.  It also seems to need to come after the include of wingdi.h.
