I've changed some things in CVS to address this problem.

I think the problem is due to calling a function that returns a 
structure (Py_complex) that was compiled with one compiler (MSVC) from 
another compiler (mingw32).  This came up before but I thought we 
addressed the problem --- apparently a few slipped through.

I've placed all needed complex functions in fastumath so that Python 
functions previously defined are not called.  This seemed to fix the 

I would like feedback from others however...
