My point is that as the master version advances in time, the baseline for submitted patches will become more and more different. Eventually a patch from the master version can not reasonably be applied against a stable branch.

That's no different to the effort involved in porting fixes on branch-1-5 forward to HEAD in CVS.

Exactly. This was not an easy chore even though CVS could give you a nice diff. If major libtool releases can occur much more often, then there should be less pain from maintaining branches.

Incidentally, I suppose we should set about defining a sensible set of goals for Libtool 2.4 reasonably soon... I'll raise that again when 2.2.2 is done.

The only two big things I can think of are

  o Better Windows support (for non-GNU compilers).

  o Multi-lib/multi-arch support (including building the libs).

We have contributed patches for some of this already. I would be happy if 2.4 popped out with just the Windows part since multi-lib/multi-arch may be a big project and requires more consensus.

It would also be nice if autoconf and libtool could work with a DTrace-fortified shell ( so that we can do some really good performance profiling on it and make it faster. There is likely some low-lying fruit that we are not aware of.

I'm looking forward to your patches now :-D

My motiviations toward libtool are mostly selfish in that libtool is vital to other software I develop and maintain. When libtool becomes a blocker, then my motiviation level becomes high. :-)

The 2.2 release is the first libtool release which satisfies all of my requirements (except for non-GNU Windows) in the last eleven years. In other words, it is the first libtool release that I feel comfortable with not using a development version in my released software. That is quite an achievement.
