        * acconfig.h: Added defines for HAVE_BUILTIN math functs for float,
        double and long double.  Added defines for HAVE libm math functs for
        float and long double.
        * aclocal.m4: Added configure checks for builtin math funcs and libm
        support for float and long double versions of the math functions.
        * config.h.in: Added undefs for math functs.
        * configure: Regenerate.
        * math/mathconf: Changed the _GLIBCPP_HAS_BUILTIN_* to
        _GLIBCPP_HAVE_BUILTIN_*.
        * bits/std_cmath.h: Added long double support.  Use builtins for
        float, double and long if available, otherwise, use libm versions if
        availible, otherwise, punt.
        * shadow/bits/std_cmath.h: ditto
