Personally I think it's a bit over kill to say don't use the headers at all for a couple of function's that needed the declarations tweeking . Dom has applied the patches for the unProject (and others) in the v1.0 branch.

I would suggest that people try these headers and give us bug reports rather then just saying don't use them. There are as up to date and you can get with support for opengl 1.1 through to 2.0.

I have personally been using these headers in Windows and Linux and have had no problems at all. All the samples in the v1.0 branch run correctly.

If there are specific problems with the function definitions , post the problem either here or on the JEDI-SDL mailing list and we'll fix it,or place IFDEF's where needed.
