We seem to have found a problem with MakeProcInstance and BC++ when compiling
Windows programs.

According to Petzold, the call should be:

lpfnRhubarbProc = MakeProcInstance(RhubarbProc, hInstance);

   This compiles fine as a C program (most of the time). (RhubarbProc is
defined as BOOL FAR PASCAL, let us say). When we try and compile it as C++,
however, we get type mismatch errors which only go away if we say:

lpfnRhubarbProc = MakeProcInstance((FARPROC) RhubarbProc, hInstance);

One would suspect that the compiler should know that it wants a far pointer
(after all, isn't that the point [pun intended] of having function
prototypes?
