sorry, wrong file...

but anyhow, I moved it to the list as suggested. I assumed it was ok to send
patches here since there is an explicit "append patch" checkbox :).

The errors are about a redundant (at least here) typedef to an undefined type
(->error) and usage of texture rectangle extensions through _NV constants which
are equivalent to _EXT constants on osx (where the _NV ones are undefined).
Fixed it through a conditional redefinition of the NV constants (i.e. when the
are undefined).
