The hpux linker and dynamic loader don't support undefined symbols. Thus, weakrefs are essentally useless as currently implemented. In principle, GAS can handle 'weak' 'static' symbols under hpux. Thus, I like your idea. However, there are issues with using weakrefs in at least some of the gthr files. Alexandre is looking at these. Dave -- J.
