opengl-1.1.0-1.tar.gz is the last version. The opengl-1.2.1-1.tar.gz name 
resulted from a mistake from my part about which version of opengl M$ was 
providing. Please consult the archives for my message explaining what was 
changed between from opengl-1.2.1-1.tar.gz to opengl-1.1.0-1.tar.gz . The 
sources didn't change. opengl-1.2.1-1.tar.gz should be removed. The 
corresponding source file could be simply renamed with a 1.1.0 version.

opengl-1.1.0-1 is really stable; I have been using it for about two months 
now. The only change I forsee is when the next version of the GLUI library 
will come out, sometime this fall.

I don't have an ftp or web site of my own, so DJ agreed to host this on the 
Cygwin site.

The need for opengl-1.1.0-1.tar.gz comes from some cygwin distribution 
"peculiarities": Cygwin, I mean cygwin-1.1.4.tar.gz, contains 3 front-end 
libraries related to OpenGL: libopengl32.a, libglu32.a and libglut32.a , 
but it does not contain the corresponding .h files, so opengl programmers 
were out of luck in Cygwin. It did not contain the glut32.dll either, 
without which libglut32.a is useless. I packaged cygwin-compatible versions 
of GL/gl.h, GL/glu.h and glut.h along with glut32.dll to resolve these 
problems. I added the GLUI library, which I find really usefull to build 
GLUT and OpenGL GUIs. I agreed to maintain this package.

If you don't want to host that package, I suggest that at least GL/gl.h, 
GL/glu.h and glut.h are added to /usr/include in the next Cygwin release.
People could get glut32.dll at the GLUT web site. I could try to have 
GLUI's author keep a Cygwin precompiled version of the library on his site. 
But I think the current packaging is more convenient for Cygwin users.
