I know you hate this kind of thing, but I think MSVC is going to complain about comparisons between signed and unsigned types in the i < n expression because 'i' is int and not GLuint like 'n'.
Same thing in patch 02/17. -Brian _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
