Add HAVE_INLINE_BUILTIN_COPYSIGN check. * c99_protos.h (copysign, fmaf, fma, fmal): Provide fallback prototypes. (HAVE_COPYSIGN, HAVE_FMAF, HAVE_FMA, HAVE_FMAL): Define if not defined and fallback version is provided. * intrinsics/c99_functions.c (copysign, fmaf, fma, fmal): Provide fallback implementations if possible * configure: Regenerated. * config.h.in: Regenerated. * math.m4 (GCC_CHECK_MATH_INLINE_BUILTIN_FALLBACK1, GCC_CHECK_MATH_INLINE_BUILTIN_FALLBACK2): New.
