See bug 24581. Some aspects are a bug (GCC doesn't handle mixed
real/complex arithmetic the way it should), some are the lack of imaginary
types (though the only use of imaginary types I know of is this one for
building up constants, and no-one on the Power ABI working group could
find any implementation for Power Architecture that actually supports
imaginary types).
