It is not in my Microsoft Visual C++ 6.0 header,
but perhaps you have a newer version?

DPlay using volatile seems a little strange,
so I thought is was wrong especially since it
was not in my version,  but then I have seen
stranger things. :-)

Because it would be incompatible (warning wise) with Winelib
applications compile with -DSTRICT since Windows doesn't
provide a special -DSTRICT version of HOOKPROC.

The application might pass a FARPROC to it and expect it
to work. Well, of course it works but it would generate
a warning.
