Hello,
I went through your commit history, and found:
http://code.google.com/p/osxnetradiant/ ... etail?r=45 - Add Q3Rad_Manual from GTKRadiant 1.5.
DON'T. IT IS FROM Q3PACK AND NOT UNDER THE GPL.
http://code.google.com/p/osxnetradiant/ ... etail?r=12 - removing that check may fix the message, but still causes stuff to be broken/cut off.
Rest seems fine. That GLint/GLenum thing may need an ifdef for the platform, though.
I went through the patch set using a merging tool, and will commit most of it to my repository.
