[BZ #721] * math/math_private.h (__copysign): Define as builtin for gcc 4. (__copysignf, __copysignl): Likewise. * sysdeps/alpha/fpu/bits/mathinline.h (copysign): Don't define for gcc 4.0. (copysignf, copysignl, fabsf, fabs): Likewise. (__copysign, __copysignf, __copysignl): Remove. (__fabs, __fabsf): Remove.
