This patch only changes arb_program_shader.c, so it cannot affect GLSL. See if
you have a HKEY_CURRENT_USER/Software/Wine/Direct3D/UseGLSL key. If it doesn't
exist, or is set to anything other than "disabled", you're using GLSL, and the
regression test is most likely wrong. If it is set to "disabled", you're using
ARB shaders, and the regression test may be correct.

Note that even if you use ARB and switching to GLSL fixes the problem, the bug
still remains valid - ARB should work as well.
