Of course, in the general (and in the OpenGL/GLUT) case you can't.

Coooool trick, really! Didn't know the -dM flag. But again in my case
it doesn't help: Depending on the OpenGL version there are #defines
or a big enum. So the only portable way without litlits would be a
small automatically generated C program that is run as part of
HOpenGL's configuration process and outputs Haskell definitions or
#defines for all needed constants. Aaaargl...
Has anybody better ideas (coding tricks, extensions for the FFI, etc.)
for a general solution to this problem?
Cheers,
Sven
