I tested the x86_64 alpha on Windows 7, and when you compile the GLUT
examples and run them directly, everything is fine. If you load them
into GHCi, they run, but you get quite a few warnings from GHC's
linker, e.g.:

This seems to be related to
https://ghc.haskell.org/trac/ghc/ticket/2283, but I've got no clue in
detail why the warning is emitted when things seem to work, and if you
read https://ghc.haskell.org/trac/ghc/ticket/9297, I don't seem to be
the only one who is confused. :-}
