One fix is to have a deployment target of `current' or some other  
tag, and to change the default deployment target to `current', then  
everything just works.  Current then selects the just installed  
libgcc_s.dylib.  If people want java to work while targeting an older  
release, they'll have to submit a patch to add the missing symbol to  
a .a-style library and then the default default can be set back to  
that release.  Geoff prefers the later bug fix.  I'd prefer that if  
the design point is to be the later style fix, then libgcc  
maintainers declare their intentions and state that any such change  
is wrong and not permitted to libgcc.  To date, I don't think that is  
the design point for libgcc.  And, if it isn't, then darwin will  
continually be hit with these issues and have to `fix' them one by  
one as they come up, which would just be annoying.  Hopefully, if I  
have misunderstood the libgcc design, someone will fix libgcc and how  
it is used in the build.
