*Purpose:
*	Declares types and constants that are defined by the target OS.
*	[Internal]
*
*Revision History:
*	12-01-90  SRW	Module created
*	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
