You are right sir, thanks! I know this is old material but I'm just following 
protocol and studying everything in the DJGPP archives that I can find to move 
forward with. I read something about "name mangling" but not sure than I fully 
understand the term right now. I'll go back and read review again. I'm using 
NASM v2.10, not sure about the rc4.
Should I apply any patches 2.03? Do they even exist? It seems like I have seen 
some mention of this.

Questions:

1. What does name mangling apply to the most? NASM/assembly, C++, or both?

2. Running DJgpp and NASM on a XP machine (dos window). I assume dos versions 
of NASM okay. Where does Win32 version come into play? I'm going to assume 
windows API related windows application programming?

Thanks for your help.

I don't believe so.  I never heard of DJNASMEX.  Google found it on one site
and Yahoo on another.  As is, it didn't compile for me.  It seems the author
set it up for C++.  That has "mangled" the names.  Someone else here might
know how to get it to compile for C++, but with a few simple changes it'll
compile for C.  (This is in the README, but I didn't read that at first.)  I
compiled with DJGPP v2.03 and v2.04.  I assembled with NASM v0.98.39 and
v2.10rc4, both for DOS.  The compiled applications seem to work.  Below is a
change list.  I didn't include the line numbers.  The files are small and
the lines should be easy to fix in a text editor.  I also didn't supply a
patch file, since you probably are unfamiliar with it.  If you don't
understand something below, ask.  If you've already done the following
changes, and it's still not compiling, then maybe you have an issue with
DJGPP.

ren *.cc *.c

 replace all .cc with .c and save
