I think we have uncovered a serious flaw in the link strategy employed
by libtool.  I can see the problem, but I don;t understand the
details... you will need to explain exactly what is going wrong to
me, so that we can hopefully figure out how to fix it.

For instance, is it always the case that whatever file is listed in
the *libgcc section of the spec file should be manually linked in by
libtool, if it has decided (for whatever reason) to pass --nostdlib on
the link line?  Even for g++, gcj?  What happens when linking a
library... linking libgcc.a into a shared library is asking for
trouble.

I wish I had a better understanding of linkers and the like :-(

Cheers,
        Gary.
