I think sysdeps/generic would be a better place for this header, as I can 
see uses for such a header in tests outside the math/ directory 
(specifically, to give strtod tests information about rounding mode 
support for different types).

I think the default definition of each macro should have a comment 
explaining its semantics.

And where you say "current", name the versions for which this is known to 
be the case (up to at least 4.8?).
