This implements the C99 copysign function as a builtin.

While I'm on the topic of fixing up our complex arithmetic,
I thought I'd go ahead and implement the C99 requirements for
complex multiplication and division.

Cool. Are you also going to switch to flag_complex_divide_method = 1

a draft patch for that? (at the time we thought it was post 4.0 material)
