Comment(by enge):
The poor performance of "pow int" is due to the fact that binary
exponentiation is not currently implemented in mpc; "pow int" just calls
"pow", and is present as a convenience function. Binary exponentiation is
on the todo list.
Except for special cases, "pow" uses log and exp, so the timing should
essentially be the sum for these two functions. Is it possible that you
hit a corner case with your experiments, or are the timings consistent
over several arguments?
Similarly, what are the arguments for division?
Concerning solaris, mpc itself builds without problems, see
