Are you talking about the thread before this mail?
http://lists.gnu.org/archive/html/libtool/2005-08/msg00085.html
If so, then would a change to the linker search algorithm fix the
issues you encountered as well?

Well, we can fix it in a different way, as Peter noted as well; the
important thing is that postdeps won't end up empty for C++.  Having it
contain -lstdc++ without the path to whereever the current libstdc++ is
it is still better than nothing in there.

Cheers, and thanks for checking this,
