Without SignalObjectAndWait() I imagine that many medium sized to large apps
would have to consider alternative threading libraries... the app I'm trying
to port uses it quite a bit to prevent race conditions. As an interested
party rather than a developer I'd suggest that the effort would be best
spent implementing SignalObjectAndWait() before worrying about pthread
compatibility, but I don't know the extent of the work involved.

For my own porting project I'm now considering at a "clean" port without any
Windows calls - fortunately we only use the thread calls and some file
system calls from the Win32 API - but I suspect that this might present a
roadblock to other projects hoping for a painless port.

In any case, you folks have done a great job with Wine and winelib, and I
thank you for it.
