Hi there.

I prepared modified include files to ease the development of programs based 
on the OpenGL, GLU, GLUT and GLUI libraries. Cygwin 1.1.2 provides 
libopengl32.a, libglu32.a and libglut32.a in usr/lib but no include files 
(.h). I prepared a bzip2'ed tar file that I would like to share with the 
Cygwin community, but for the moment, I don't have my own ftp server. The 
tar ball is about 200K; content:

	usr/local/include/GL/glut.h
 From http://reality.sgi.com/mjk_asd/glut3/glut3.html; modified to add 
__attribute__ ((__stdcall__)) to the declaration of functions to enable 
linking with glut32.dll via usr/lib/libglut32.a . Jerome G. Benoit provided 
hints about how to do it and provided an example; thanks Jerome!

	usr/local/bin/glut32.dll
 From http://reality.sgi.com/mjk_asd/glut3/glut3.html; not modified. Move 
to some directory in your path or add usr/local/bin to your path.

	usr/local/include/GL/glu.h
Modified version of usr/X11R6/include/GL/glu.h from 
ftp://sourceware.cygnus.com/pub/cygwin/xfree/xc-4-binaries/xfree86-4.0-devel.tar.bz2 
to add __attribute__ ((__stdcall__)) to the declaration of functions to 
enable linking with glu32.dll via usr/lib/libglu32.a .

	usr/local/include/GL/gl.h
Modified version of usr/X11R6/include/GL/gl.h from 
ftp://sourceware.cygnus.com/pub/cygwin/xfree/xc-4-binaries/xfree86-4.0-devel.tar.bz2 
to add __attribute__ ((__stdcall__)) to the declaration of functions to 
enable linking with opengl32.dll via usr/lib/libopengl32.a .

	usr/local/include/glui.h
 From http://www.cs.unc.edu/~rademach/glui/; not modified. Header file for 
the GLUI tool kit version 2.0 beta.

	usr/local/lib/libglui.a
A static library compiled from unmodified sources of the GLUI tool kit 
version 2.0 beta, found at http://www.cs.unc.edu/~rademach/glui/. 
Compilation with -O3 optimization. I highly recommend this very useful tool 
kit.

Modified sections of the .h files are bracketed by
#ifdef (__CYGWIN__)
#endif

libglui.a, libglut32.a, libglu32.a and libopengl32.a interface with Windows 
NT/2000. I don't know about Windows 95/98. No X server required.

I will email an attached copy of the tar ball upon request.
