I am a new Windows 3.0 developer using Zortech C++.  I've run up
against what I will call a beginner's configuration problem.  I recently bought
Petzold's book and keyed in ENVIRON.C which references "environ" in the
code.  This is a pointer to the environement.  It wouldn't compile.
The file includes <stdlib.h> where "environ" is supposed to be
defined.  It is, but in \windev\include\stdlib.h, and not in
\zortech\include\stdlib.h which is what I am getting since I have my
INCLUDE env. var is set to Zortech's.  I redefined INCLUDE to be only
the SDK includes and Zortech complained about a decl. using the
volatile keyword... My question:  What must I do?  Must I go in
and "condition" any SDK header file so that it finally pleases the
Zortech compiler, or do I use the Zortech supplied header file and
change "environ" to reference the Zortech pointer to the environment
(envptr)?  Or what?  How should things be configured?

This raises another question:  What if I want to use some of the
Zortech libraries.  Can I along with the windows libraries?  What
problems must I look out for?
