Hmm..it appears that AIX uses the suffix '.a' for dynamic shared libs.
How nice :-(. Well that issue's solved.
However if I compile code with either g++ or xlC v5, then link against
the xerces-c libs in the prebuilt download, I get link errors. None of
the xerces-c APIs can be found.
Is it possible that g++ and xlC v5 use different name-mangling
algorithms from xlC v6, which the binary xerces download was built with?

I'd still *really* appreciate any suggestions on this.
