OK apart from the removal of the inline definition of __copysignl.  That 
inline definition is still relevant in the absence of changing all calls 
to __copysign* to call copysign* directly so the compiler can inline them 
(and if changed to call copysign*, which I think would make sense, it 
would be desirable to run build-many-glibcs.py tests to make sure this 
doesn't introduce linknamespace issues).
