Gosh - that was a quick reply!

I did see the feget/setround option in FPU.h. The trouble is, finding an
*implementation* of that. 

It seems to be in a system header called /usr/include/fenv.h, and is not
inline. It's therefore in the library files, which of course I can't include
in Javascript. 

Emscripten has its own implementation of libc and libcxx:
https://github.com/kripken/emscripten/tree/master/system/include/libcxx

And this issue of what to do about rounding modes in that implementation has
been discussed here (regarding another project):

https://github.com/kripken/emscripten/issues/540

Regarding IA_force_to_double, I've already dropped that, since when
compiling with Emscripten we undefine the __GNUG macro (for just that
reason).
