I believe the nvidia compiler failing to conform to performing to spec. I
double checked the glsl 1.50 specification for keywords ( section 3.6 ) and
the keyword signed is not mentioned. However I did notice that unsigned is
a reserved keyword, so the behavior nvidia has is sensible since most
c-like languages reserve this keyword.
