I think it's gcc 3.3.5 and x86 specific. I'm not positive about the .5
though. I've been building on darwin ppc with 3.3 and it's fine, and
it fails on openbsd too. But it's also successful on gcc 4.1. I've
addressed it with using sprintf, since 1.22461e-16 is close enough to
0.000000 for me. But openbsd still gets one failure, a +-0.0 problem,
which is already present in other areas.

With gcc (GCC) 3.3.5 20050117 (prerelease) (SUSE Linux) I get:

OTOH gcc 4.1 works fine. Both on x86/linux, 32-bit.
$ perl -Ilib t/pmc/complex.t

not ok 27 - exp of complex numbers
