	Hi... I'm an experienced C programmer, but new to C++ and Windows programming. I 
recently bought a book on Win95 programming, and it contained some source code for a very 
simple example program of which I'll include later. I've tried to compile this simple 
program, but failed. I get spammed with several "undefined reference to" error messages. 
	Also, on another note, is there a way to download all the Cygnus docs off the net 
without doing it page by page? This is extremely annoying. DJGPP has a very informative 
and useful INFO command. I don't want to spend hours on-line every time I want to refer to 
the docs, or have a folder full of a jumble of documents with a confusing list of pages.
	Okay, back to the code... They are listed as follows. 
	1: compile command line. 
	2: LISTING2.H 
	3: LISTING2.CPP 
	4: LISTING2.RC 
	Any help will be greatly appreciated. Thanks... ^_^
