           Summary: Make the new symbols weak symbols
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libobjc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: js-gcc@webkeks.org


Hello,

gcc 4.6 introduces a lot of new symbols like objc_setProperty, objc_sync_enter
etc. Those are often already provided since they were always missing, but
support for e.g. @synchronized was always there. This creates conflicts now
when using gcc 4.6, thus I would suggest to make those weak symbols in 4.6.1.

Except I think it was a bug that someone would implement them since it was part
of the ABI.

Yeah, right, it is a bug to supply the symbols that libobjc has been missing
for about 10 years, so that you can actually use basic ObjC1 stuff like
@synchronize, which gcc always claimed to support… And it is a bug to provide
them if libobjc has been dead for years… And it sure is a bug to not wait for
the bug reports to be actually cared about after they have been ignored for
years…</sarcasm>

Seriously, you can't assume that people just accept broken stuff for almost ten
years and then when someone finally fixes them (thanks a lot for your work on
the new libobjc, Nicola!) assume nobody did something to work around it in the
meantime, after it was told countless times in bug reports that nobody cares.
