This is a missing c99 method. Could you move this one back? Either we should
keep that one here or we should move all of them to floating_point.h. I would
prefer keeping this one here along with the other methods that are missing on
Windows and leave floating_point.h for dealing with differences between platform
provided methods.

Done.
I moved it to c99_support_win.cc, though, so it is not inline method as I think
it is got quite big now. Is that what you had in mind?
