When using ltdl on Windows to load plug-ins there is a problem with the
name mangling system. The info.name field is only set if libltdl finds a
.la file. Just the DLL won't do. The result is that symbols cannot be
found becaus libltdl looks for the plain name (without prefix).
The fix should be a matter of moving the code that filters out the
extension to before the branch between la and non-la files. I tried it
here and it works lika a charm.
Please post the patch (with `diff -u'). Thank you.
Patch included.
