[osg-users] fails compilation on linux (Ubuntu Feisty Fawn)

[Art Tevs]

Hmm, seems to be a good idea, since it would really
define only those things, which are not defined.

Now we need somebody to merge this for every define in
the osg ;-) I think it would be faster to write a
script to search for #define GL_ and to replace it
with the proposed macro.
