For Windows 2.0 development, I used the following patch to windows.h (I
did not yet get the Windows 3.0 SDK). When defining WINEXPORT before
including this modified windows.h, you can forget about exporting the
window procedures in your .DEF file when you declare all Window
procedure as "LONG CALLBACK WndProc(...)" etc.
