This is the same question that I asked Gaby. I had suggested
modifying std_cmath.h to perform the static conversion if the system did
not provide sqrtf, but I understood Gaby's reply to me earlier to mean
that those __builtin_xxx functions must be available unconditionally in
std_cmath.h. I may have misunderstood.
