	G++ and xlC are not compatible.  The name mangling and exception
handling are completely different.  One cannot use a G++ library with xlC
and one cannot use an xlC library with G++.  Everything is compatible at
the C Language level, but not C++, which is much more compiler-dependent.
You must compile and create the shared library using G++ if you wish to
use it with G++.

Sorry, David
