That's a problem with the current Cygwin headers: They are simply lying,
the DLLs under WinDoze only implement OpenGL 1.1 and GLU 1.2.2. The rest
is available as extensions, but HOpenGL 1.03 doesn't use the extension
mechanism (yet). A quick fix would be:

    * In HOpenGL's configure, replace the line '#ifndef GL_VERSION_1_2'
      with something like '#ifndef ThisIsVeryUnlikely'.

    * Re-run configure and make.

Given this situation, I should really rewrite the autoconf stuff for
version detection... *sigh*
