I did this for the ia64 code since the whole libm in theory could be
replaced and then it handles all the error stuff itself.

If your implementation really does everything the wrapper +
implementation does today (and the test suite does not test everything)
then keep the code as is, make w_sqrt empty or the other way around.
But you have to be aware that any ommission means binary imcompatibility.
