I'll leave the decision whether to include the testcase into glibc or not to
Ulrich, I'm not involved with glibc these days too much.
And I'm not sure if there are any supported targets that do currently use
math/s_fma*.c.
BTW, your implementation will do the wrong thing if you call say
fma (DBL_MAX, DBL_MAX, -__builtin_inf (""));
will I think in your implementation return NaN, while it must be -Inf.
