branch-1-5 ltdl finds these symbols with the preopen loader.
HEAD tries with the dlopen one, and then fails.
I think this is due to the order in which lt_dlopen tries the loaders,
and for some reason or other we changed that order (deliberately?) in
HEAD over branch-1-5.
At least with this crude hack I can get the failure to disappear.
What I don't know yet is how to fix this right, nor why this patch would
even be needed: glancing at the documentation, dlopen(NULL) should just
work.
Cheers,
Ralf
