IIRC, ar currently cannot create archives that store path info, but can
handle them. I believe libgcj.a is carefully constructed to work around
this. Strip, however, is more "brute force" about things and does exactly
what Matthias describes, hence the problem.
Matthias, is there any way that someone can lobby to change the name of
that object file to something like sqlDate or something else unique? It
seems odd that they would even want the same filename to be used with only
a path to differentiate the two, especially knowing the limitations of
the GNU tools like ar and objcopy/strip. I can probably provide a patch
that accomplishes a renaming of the file if nobody else has time...
