Re: problems with libX11.a

Harold,

Sorry I forgot about that part.  The 'nbreaker' demo seemed to be the only 
demo causing problems and we were under some pressure to get the project 
built, so we moved the 'nbreaker' demo out of the demo directory so it 
wouldn't try to be built with the rest of the project.

I did some looking before removing the demo and found that 'GR_PIXMAP_ID' 
is NOT defined in any header.  I found a reference to 'GR_PIXMAP_ID' in the 
file 'original_mini-x.txt' which discussed all of the TYPEDEFS in the 
project.  This led me to the 'nano-X.h' header, which defines all of the 
other defines listed in 'oringal_mini-x.txt.'  I noticed that the comment 
on the typedef for 'GR_WINDOW_ID' mentioned that it was a "window or pixmap 
id."  I am assuming that if you were to define 'GR_PIXMAP_ID' in the same 
fashion as 'GR_WINDOW_ID' that you might be able to get the project to 
build...we just didn't have time to explore that option.
