This is the same than on my Mac.

The API has not changed between 10.4.11 and 10.5.x. Now I'm completely confused 
why I get an error if I mix up "int *" with "GLint *" and you don't get an 
error. Is there a third OpenGL library on your Mac, maybe it comes with Fink? If 
that is true can you find for me the gl.h please, somehow like this

bash$ find /sw -iname gl.h

or even better, can you send me the output of this please

bash$ find / -iname gl.h

I will do some tests and write a small script and/or program we can then play 
with (if you want to). I suspect something is being set wrong.

So I was wrong ;)

Yes I know that you're working on the Gnuplot backend, I sometimes have a look 
at that many changesets you send ;) Thanks for them! But if you don't mind I 
send the one or more source file to you in the near future for tests on a 10.5 
system - currently nobody else joined up as volunteer ;(
