It does seem like a good idea to separate the two purposes, but 
libltdl will still need to be able to deal with existing .la files 
which don't observe the new scheme.

We can also take the easy way out, which is to simply filter the names 
in libltdl.  Filtering the names is quite easy, particularly when it 
is done at the lowest level (just before the LoadLibrary call) so the 
filtering is platform-specific.
