You want to change existing behaviour, not me.  The Solaris and HP-UX guys 
already stated what they do, and are unlikely to want to change behaviour.  
I don't think we can change the gABI to be more explicit about weak 
symbols (not the least because Solaris and HP-UX already differ in the 
details), so I think we're left with discussing it here.


Ciao,
Michael.
