Subject: resolving weak symbols.

HI,

Support I have a static archive libfoo.a that has a weak sym, call it quux.

And the link line I have is

gcc -o foo -L. -lfoo -Wl,--as-needed -lbar -lbaz

Where libbar.so and libbaz.so also have the weak symbol quux.

Then the executable foo has a dynamic dependency on both libbar.so _and_
libbaz.so.

Is this expected behavior?  Is there a way of forcing exactly one of
libfoo.so and libbaz.so to be used?

Thanks,

Tom
