Note that you haven't included <complex>, so template std::complex is
not defined.  No excuse for an ICE, though.

Anyway, if you #include <complex>, you'll still get template complex
declared in the global namespace, even if you compile with
-fhonor-std.  std/complext.h is not namespace-aware yet.
Contributions are welcome :-)
