Well, here is my latest MAKE output capture.  This one I find
a little hard to explain also, and I even checked the FAQ this 
time! :)  Anyways, here's the problem:  I've written the basic
outline of a simple event driven GUI framework for my program.
It compiled fine and dandy till I tried adding in some very minimal
Allegro support (i.e. I added enough Allegro routines to ideally 
fill the screen with one window with absolutely nothing in it and
no functionality).  Well, as soon as I wrote a test program, and 
started linking in the Allegro library, I got a ton of undefined
references and a whole bunch of multiply defined refernces.  Any
ideas?  All problems are link related.  I suppose it's a coding 
problem, I'll be thorougly reviewing my code tomorrow, but any
help would still be appreciated!
