Let's *ping* for Richard.
with the sincos infrastructure in the middle end (I think all patches
are now in the trunk), this speeds up the Polyhedron fatigue test a lot:
~28.3s => ~18.3s (35% faster).
This can be seen at the page
(The patch was applied for one day.)

As $subject says. The cbrt builtins can be used to expand x**1./3. to
cbrt, the other two are on-top of the sincos patches.
Bootstrap / regtest running.
Ok if the sincos patch(es) go in? How can we tell that the target
supports sincos? (I guess we would need a configure check for that?)
It was not clear to me the consequences of the question about needing a
configure check. Has that been addressed?
Tobias, did you test this?
