That's not the case: The DLL is still 1.1, even in 2003. :-) All cool new
stuff is available only via the OpenGL extension mechanism. As a start
you can read e.g.

Linux and most *nices are a bit different in this respect. The OpenGL
libraries are normally 'real' 1.{2,3,4} ones, although the extension
mechanism still works, too.

What version of GHC are you using? Upgrading to 5.04.2 could help here.

Lying OpenGL headers again...

Yes, that seems to be the case. The relevant line from your configure log:

    checking for library containing glutMainLoop... no

I don't know what's wrong with your Cygwin setup. I've installed a fresh
Cygwin a few days ago and everything is fine. I don't have a full
installation, though, only the default stuff + development + graphics, IIRC.

That's OK, the only trouble is that they sometimes see different headers.

Does HOpenGL-1.03 work with your Mandrake Linux? I'm developing on SuSE
Linux, but there shouldn't be any differences.
