2000-06-13  Steven King  <sxking@uswest.net>

        * acinclude.m4:  Fixup some of the builtin math tests and add tests for
        __builtin_fmod* and test libm for fmodf, fmodl or _fmodf, _fmodl.
        * acconfig.h: Add entries for fmod*.

2000-06-13  Branko Cibej  <branko.cibej@hermes.si>

        * bits/std_cmath.h:  Fix typos in tests (*_FMODFF -> *_FMODF).
        Test  *_MODFF not *_MODF for modf(float, float*).
        (modf(float, float*)): Remove reference to _C_legacy.
