You might want to look at  numarray-0.9/include/numarray/genapi.py and
see if you can modify the macro generation into something xlC can
stomach.  

Right now, the call consists of these parts:

1. A cast of the API jump table pointer and function ID to a pointer to
a function with a particular signature.

2. Code which checks to see that the API pointer has been initialized
and gives a fatal error rather than dumping core if it has not been
inited.

The macro generation Python code looks like:

PSEUDO = """
#define <function> (<module>_API ? (*(<rval> (*) <proto> ) <module>_API[
<num> ]) : (*(<rval> (*) <proto> ) FatalApiError))
"""

You can simplify it to this by eliminating part 2:

PSEUDO = """
#define <function> (*(<rval> (*) <proto> ) <module>_API[ <num> ])
"""
 
And then re-install with:

python setup.py install --gencode

Beyond that,  you're in new territory for me.   Good luck!   Let us know
how it goes.
