Oh well, it only means I will have to have two GC scanning loops: one for Windows NT where the top mark bit will be set, and another for Windows 3.1 where the top bit will be clear when marked. Probably not that serious after all. By the way, do you know if using TLS (thread local storage) would be a way to provide separate instance data for a DLL under Win32s? Theoretically, it seems like it should work. Thanks, David There is 1 Reply.
