Anyone know of a decent C99 fenv.h implementation for MS compilers?
I imagine this wouldn't be difficult to do; I'm just looking to save some time.

I don't know of any implementations and I doubt any exists. Although Visual Studio has the _controlfp() function and a number of related preprocessor pragma's (float_control(), fenv_access(), fp_contract(), I don't think you can use them to create a conforming fenv.h implementation.
Sad as it is, Visual Studio is not a C99 compiler, and probably never will be.

Pretty much this. Visual Studio doesn't care about C99. – Puppy Aug 12 '10 at 08:20

Thanks for the replies. I suppose then they couldn't care less about portable validated numerics. – defube Aug 12 '10 at 19:42

1This. Visual Studio is not (and probably never will be) a C compiler. – Stephen Canon Aug 12 '10 at 21:41
