* bits/std_cmath.h: Tweaks.
* math/mathconf.h: Tweaks and fixes for HP-UX 11.
(sqrtf): Define away iff !builtin and !in <math.h>.
(sinf): Same.
(cosf): Same.

At some point this directory should be converted to c++, the
autoconf tests should be run by the c++ compiler (not c), and
<cmath> should be used instead of math.h.
Move declaration of nan() here.

Finish up FreeBSD4.0 support.
