> This is will never be fixable for darwin9 short of using a newer linker as the
weak linking works perfectly on Darwin9, when the semantics are as per the
vendor's design (i.e. the exe link is done against a library containing the
weak symbol, either real or dummy). The weak reference then behaves as
expected at runtime.
There is a work-around to make Darwin9/Mach-O behave more like ELF weak
(although this is NOT likely a good idea for general applications, it seems
reasonable in the confines of this test).
