IBM CSet does. But I don't see any reason why *any* compiler shouldn't !

You can turn every textmode application into a PM program when you make use
of redirected stdin/stdout. But I don't see any reason why you should do
that hack.

A common OS/2 fullscreen program doesn't make use of PM functions like the
clipboard for example, and - more important - there *are* native PM message
readers (FleetStreet, Sqed/32, MyEd, PMMsged).
