I can't explain the Opts.C99 (fesetround is provided by conforming C++11 implementations too), but I think I was just trying to capture the fact that decent hosted platforms support fesetround but freestanding ones don't (not having any library).

Supporting "C89 but we also have math.h" (or more realistically "C++03 with math.h") wasn't really something that interested me: users should be encouraged to write to standards.

Cheers.

Tim.
