We don't support weak symbols under hpux, so all the weak related
failures can be safely ignored. A number of weak related tests
have been added recently and they don't detect properly the lack
of compiler support for these symbols.

There aren't any failures in the g++ or gcc testsuite under hpux that would
explain your problem with OmniORB4. The remaining g++ fails are caused
by testsuite problems and hpux not supporting weak symbols.
