Thanks for taking the time to put those archives on your FTP server.  I 
was able to find it and get them.  Orbital mechanics are still holding.

In an earlier mail you said that #$ should work for #defined constants 
in the form

#define <name> <expression>

Perhaps I was doing something wrong, but this did not work for me:

CL-USER> (open-shared-library 
#<SHLIB /System/Library/Frameworks/AGL.framework/AGL #x6493426>
; Evaluation aborted
; Evaluation aborted
; Evaluation aborted

AGL and OpenGL have a lot of #define stuff which is what concerns me 
the most.  I would like to create a Lisp file that has something like 
this in it:

(in-package "AGL")
(defconstant +colormap-tracking+ 210  "Enable or disable colormap 

CL-SDL has a lot of stuff like this in its opengl.lisp file.  What I 
want to do is create an abstraction layer between OpenMCL's FFI and my 
code so that my code can work directly in an application that uses 
CL-SDL.  I don't want to use CL-SDL itself because there is stuff I 
don't need in there and I also don't want to drag in UFFI.

I hope this doesn't all sound too crazy.
