// Author: Edward Hutchins
// Status: Freeware
// Revisions:
// 06/06/90 modified HUGE to LARGE to preserve compatibility with math.h
//          also nested windows.h include to prevent modifications on the
//          actual source file - Ed.
// 10/01/90 added CONST and CONSTP,NP,LP,HP and a few comments - Ed.
// 08/28/91 added EXPORT and SEGMENT - Ed.
// 10/28/91 added DLLEXP - Ed.
// 11/02/91 posted on Compuserve - Ed.
// 11/09/91 added REGISTER - Ed.
// 11/19/91 added ATOM pointer types - Ed.
// 01/02/92 fixed to work with win31 beta II - Ed.
// 01/03/92 added #define STRICT before #include <windows.h> - Ed.
// 01/03/92 #included <windowsx.h> - Ed.
// 02/26/92 added check for NOSTRICT - Ed.
// 02/29/92 added the neat macro wrappers BEGINMACRO and ENDMACRO - Ed.
//

//
// include WINDOWS.H, if needed
