I'm discussing ::pow() because that is what the reporter wanted V3 to
use. I emphasize against those, and I would strongly advise against
any patch that does that. Which is why I'm telling you that upfront
before you waste your time in that direction.
The only fix that I should have applied is to make __cmath_power()
inline. Any other if or #if are just papering over the fundamental
problem. That is not fix.
