	Hi.  I'm working on a graphics project on an sgi, and have been
trying to use C++ (AT&T, until I build g++) for a system that works with
the 4sight graphics calls.

	It's not working.

	Assuming that I have a "normal" set-up, I took the program
ocatahedron, found in ~4Dgifts/examples/glpg/ch02/octahedron.c, which works
fine when compiled with cc and the required libraries, and compiled it with
CC (the C++ compiler).  I get a  blank window, and "ERROR #4  ortho:
ERR_BADWINDOW" on my tty.  I'm assuming that this is a bad thing, since
I don't know where documentation for error messages goes.

	I snagged the C file, translated by cfront, did some sed'ing
to minimize the differences between the two files, commented out the
call to _main(), compiled with cc, and the problem is still there.
 
	As far as I can tell, there aren't any differences between the
two files.  I put absolute paths in the #includes, to make sure the
same headers were getting included, and such, changed the variables
back to the way they were originally, and as far as I can tell, the
only differences between the original main(), and the cfronted main()
is tabs, and resolved macros.  I still get errors and a blank window.
 
	Help?  Does anyone have C++ code using gl calls which works?
 
	-rj
