Yes, it should be possible to just keep that.  More or less (i.e.,
modulo bugs in the new macros).

You can update that to
  LT_INIT([dlopen])
  LT_CONFIG_LTDL_DIR([libltdl])
  LTDL_INIT([convenience])

but just keeping it as it is should work, too.

At the moment there is no definite guide for upgrading, but searching
for the old macro names in the manual should provide at least some hints
(yes, this is more of an excuse, sorry about that).

Cheers,
Ralf
