One issue which Lee rose but was not addressed quite well is that you'll 
need IN ADDITION to the above mentioned stuff the windows.h plus some 
other windows specific include files (which incidentally have to be 
processed by an utility which comes in RSXWDK package), PLUS the resource 
compiler from microsoft RC.EXE.

Note that this is a BARE MINIMUN as the windows API documentation must be 
get some other place as well.

As Lee pointed out if one had to get one windows compiler for getting all 
this stuff, it ist wiser just to stick with that one (execpt if one finds 
an absolute advantage in using DJGPP instead).

Up to this point Microsoft has not released RC.EXE nor its necessary 
include files in the public domain, so speaking strictly, one had to be 
owner of a 16/32 bit compiler or at least the Windows SDK (which 
presently is not being sold separately anymore), in order to use the 
RSXWDK package in full.

I expect this clarify a little more Lee's question.
