complexobject.c optimization error on SGI

[Robert J. Harrison]

On an SGI (IRIX64 6.5, MIPSpro Compilers: Version 7.3.1m, -n32)
Python-1.5.2/Objects/complexobject.c does not compile correctly 
with optimization.  The problem shows up as a bus error in
PyComplex_ImagAsDouble when importing Numeric Python.  All works fine 
when this one file is compiled with -O0 (-O1 and higher fail).

Since we use the complex arithmetic it would be nice to compile
it with optimization.

Has anyone got a workaround?
