would it be possible that you test this new functionality and check

whether it works for you?

I finally got a chance to give it a shot, and am running into problems.  I'm a cvs checkout from yesterday.

It looks like the problem with lt_dlopenext() -- we always call it with an absolute path to a dso, minus the extension.  Before the patches from Gary, this worked.  Now lt_dlopenext() always returns an error in that case, and the error returned from libtool is "file not found".  I unfortunately don't have time in the next week to investigate further.  System details:
