Good point.  I was extrapolating.

The section at the end of ltdl.h labeled, "Binary compatibility with
old libltdl" seems redundant -- we've just bumped the revisions such
that 2.0 libltdl will never be runtime loaded into an app linked
against 1.5.x libltdl.

Okay, we have 2 paths:  Remove all deprecated functions and get our
clients to clean up their code, instead of wasting cycles on setting
unused malloc pointers, and seeing a deprecation warning on every
run of a program that is still trying to use the original non-working
mutex APIs.  Recall, that on the transition to 2.0, clients will
already need to fix their code a little and recompile freshly with
libltdl.

Alternatively, we can add more functions that answer to the names
of APIs that were removed in the transition to 2.0 for reasons
explained in my earlier mails, and bug the users with additional
deprecation warnings.

Currently, we do a bit of both which is plain wrong.  Since 2.0 is
plainly a major upgrade, I think the first option makes more sense.

Oh, *blush*.  Yes that was a little rash.  Removing all trace of it from
the documentation is still the right thing IMHO.
