I kinda sorta tend not to care about windows :-) But as to rint/nearbyint, what they do depend on the current rounding mode, and given that's eventually in a library I consider mucking with fpu mode risky, especially for a reference software renderer. On the gpu the problem is different, but that code is not used anyway (but I should check const folding now that I think of it).
