here's a question:

Consider an application which configure script checks for the existence
of the fenv.h header and functions defined therein.  It will find that
the header exists and that, for instance, the function fesetround
exists, too.  However, the fesetround will always return -1.  This might
result in some applications not being buildable anymore in a working
way.

Wouldn't it be better to fake the "set"-type functions to always succeed?
Or, to drop the definitions of the set functions entirely?
