Almost everything from here...

...to here is tangential to the test, since the test only needs to validate
the behaviour of gs, not the entire program.  I'd cut it down to just:

    gs = piglit_compile_shader_text(GL_GEOMETRY_SHADER, gstext);

Then you should be able to drop the vstext and fstext globals.

With those changes, this patch is:
