*       02-01-91  SRW   Removed usage of NT header files (_WIN32)
*       02-28-91  SRW   Removed usage of ntconapi.h (_WIN32)
*       04-09-91  PNT   Added _MAC_ definitions
*       04-26-91  SRW   Disable min/max definitions in windows.h and added debug
*                       definitions for DbgPrint and DbgBreakPoint(_WIN32)
*       08-05-91  GJF   Use win32.h instead of windows.h for now.
*       08-20-91  JCR   C++ and ANSI naming
*       09-12-91  GJF   Go back to using windows.h for win32 build.
*       09-26-91  GJF   Don't use error.h for Win32.
*       11-07-91  GJF   win32.h renamed to dosx32.h
*       11-08-91  GJF   Don't use windows.h, excpt.h. Add ntstatus.h.
*       12-13-91  GJF   Fixed so that exception stuff will build for Win32
*       02-04-92  GJF   Now must include ntdef.h to get LPSTR type.
*       02-07-92  GJF   Backed out change above, LPSTR also got added to
*                       winnt.h
*       03-30-92  DJM   POSIX support.
*       04-06-92  SRW   Backed out 11-08-91 change and went back to using
*                       windows.h only.
*       05-12-92  DJM   Moved POSIX code to it's own ifdef.
*       08-01-92  SRW   Let windows.h include excpt.h now that it replaces winxcpt.h
*       09-30-92  SRW   Use windows.h for _POSIX_ as well
*       02-23-93  SKS   Update copyright to 1993
*       09-06-94  CFW   Remove Cruiser support.
*       02-06-95  CFW   DEBUG -> _DEBUG
*       02-14-95  CFW   Clean up Mac merge.
*       03-29-95  CFW   Add error message to internal headers.
*       12-14-95  JWM   Add "#pragma once".
*       02-24-97  GJF   Replaced defined(_M_M68K) || defined(_M_MPPC) with
*                       defined(_MAC). Also, detab-ed.
