My fault, time was very short last week and I applied your patch 
(badly) by hand.  Thanks for catching it.  Hopefully now fixed :-/

First one is the internal name (with a `_' prefix on some systems), and 
the
second one is the symbol name passed to lt_dlsym (always without a 
prefix).

That's just the way it has evolved.  This release is as much about 
refactoring and tidying libtool to ease the maintenance burden as it is 
about any new features (although we have those too).  I'm planning 
another alpha by the end of the week if I have time to fix the mkdir_p 
issues, and we may need another after that if Scott and Alexandre 
resolve to change the way linux uses pass_all or file.  If you want to 
submit a patch before that, I'd be inclined to accept now rather than 
wait for the next full release.

Cheers,
        Gary.
