Hmm, unfortunately I didn't notice that in your last patch, but why do you 
warn about vfoo1f and vfoo1g now? In both cases the variable is defined, so 
dereferencing is no problem, even if it is weak, or? Jason reminded me of 
that fact and I added the DECL_EXTERNAL (newdecl) && DECL_EXTERNAL 
(olddecl) check. Do you disagree?

Franz.
