Thanks for catching these!  We should capture the concensus in HACKING...

No, because people might like to use CVS versions (once their favourite
patches have been incorporated for example), and we want to support them
too.  The serial on each M4 file should be incremented each time the
interface changes, independently of release schedules.

For M4 files on branches, we ought to be using cvs like `.' delimited
#serial numbers, otherwise a busy branch might end up with a serial
number that overtakes the trunk :-o  Only version.m4 does this right at
the moment.

Same answer -- in order to support people who use CVS versions of
libtool, the libltdl library versions should be incremented at the time
we change the interface.

Supporting branched revisions is more difficult here, because we need to
be sure that a branch release doesn't 'catch up' with the trunk and
start using the same interface numbers that were once used on an older
trunk revision.  I think the best way to prevent these problems is to
incorporate the branch number in the libltdl soname.  I think -release
is ugly, but it is all we have right now.  Releases from branch-1-5
haven't used it thus far, and 1.5.16 doesn't break binary compatibility
with 1.5.14, so for branch-1-5 it is too late already I think.

For branch-2-0, I think we should start using `-release 2.0' right away.
Opinions?

Cheers,
        Gary.
