So, let's begin from the end: there is nothing *unimplemented* as far as
operator* is concerned: have a look to section 26.2.1 of the Standard, there
are *no* overloads taking two different template parameters.

The first issue, serious, does *not* occur on mainline, and seems a very nasty
compiler bug: in fact, the library code for pow(complex, int) is *identical* in
mainline and 3.4. Also, there are no specializations for long double vs double
and in presence of different behaviors, this is alone a very good reason to
suspect the compiler.

Gaby, what shall we do? I'm afraid that the compiler people will not be able
to work with the full std::complex testcase :-(( but a recategorization seems
rather obvious to me.
