/* Procedure declaration macros.  These are defined to 'correctly' define
   a procedure for the version of Windows for which we are compiling.  These
   macros are to be used for both the prototype and for the actual definition.
   For example:

   DCL_WinProc(foo);                -- prototype for a foo().
   DCL_WinProc(foo) { return 0; }   -- code for window procedure foo().

   (This is also to compensates for all the discrepancies in the docs.) */



/* Provide standard declaration for WinMain().  Although WinMain() is a
   conceptual constant throughout the various windows implementations,
   the exact declaration varies (considerably) from release to release. */

   declaration for a window procedure changes even more quickly than
   WinMain(). */
