Yep, libstdc++ is one of the most visible cases of this problem.  The thing
is, we have to tell libtool which directories to search, and there's no way
for it to know which directories are "transient" and shouldn't be remembered.
It's a well-known problem and people would love for it to be solved.

The .la files are the only place where these paths are recorded.

I have no idea.  I don't think I've ever seen that before.


There is a separate mailing list for libtool, linked from its homepage,
