Sounds like importing winspool.drv in wineps creates a circular load
dependency (user32->gdi32->wineps->winspool->comctl32->user32). We
could probably be a bit more clever about loading wineps only when
really necessary; OTOH there is no reason for winspool.drv to require
comctl32. Something like this should fix it (completely untested, so
it's probably broken):
