--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Those warnings just match a predefined list of names and suggest the right
header. If 'sincos' is not found, it says to include <math.h>, there's no check
for which OS you're on or whether math.h has been included already. It's much
simpler than that.
Yes, sometimes including <math.h> isn't the solution, but it does say "or
provide a declaration of sincos" so it's not wrong.
