Thanks. I actually had it working before, but now I can't configure it. 
I can't remember which directory I placed the!

I'm kinda having some trouble following the directions. You wrote very 
clear directions but probably didn't follow them well ;-)
 I could not get config/configure (is that what you are referring to as 
'autoconfig'? Or is that a new script?)  to find my no 
matter where I put the plugin directory (although it did create the 
Makefile. )

But anyway.... Since I don't really have a unix specific plugin, I want 
to put it in Cross for now and I'll try that.

Have you used VMMakerTool? If so, how do you use it to generate C files 
in the Cross directory?
