* sysdeps/i386/bits/mathdef.h (FP_FAST_FMA): If the GCC 4.6 port has
fast fma builtins, define the macros in the C99 standard.
(FP_FAST_FMAF): Likewise.
(FP_FAST_FMAL): Likewise.
* sysdeps/x86_64/bits/mathdef.h: Likewise.
* bits/mathdef.h: Update copyright year.
* sysdeps/powerpc/bits/mathdef.h: Likewise.
