Those two calls are actually only available on Windows 98/Me and Windows
2000/XP so they can't be used on Windows CE. I guess this could cause a
problem if someone tries to use the extension on Windows 95/NT 4. I haven't
got a clue what would happen, I guess it would only crash if they tried to
execute the call, the rest of the library would work ok.
I will add them into the win32gui module as well though.

I've just checked on the Microsoft website and these calls have been added
to MFC, but I guess that they were added as part of the latest version of
MSVC++ as my version (6) doesn't have them in.
