We need it if we ever want to use libtool unless you want to include half
of libtool into CVS.

It's really the same as keeping all of the C source code in one file, you
don't do that either. IMHO, it's a matter of logical organization,
modularity etc. I find setups organized like this much more readable. Many
tests in configure don't interface to config.cache properly;
unfortunately, fixing that makes the tests longer. I don't think a 5000
line file of shell and macro processing is really what you want.

I already fixed something there.


Well, I'm not proprietory on any of this, I'm just following the book. Let
me know...

Huh?  libtool doesn't require automake; I've been using it quite
successfully for libjpeg without any automake.

My impression so far of automake is that it imposes a ton of mechanism
and unpleasant restrictions (like, say, not being able to make INSTALL
an absolute path, as any half-sane person would do) in return for darn
little usefulness.  I'm going to want to be convinced that it's a good
idea for Postgres...

Okay, then I'll have to investigate more. I'll tell you what, I'll change
`aclocal' to `cat' for the time being. But I'd sure hate to have all the
macro definitions in one file. As someone else once said, you separate
what you test for from how you do the testing -- implementation hiding.

Okay, just to put my two cents in here ... when I played with libtool a
little while back, it was my impression that *without* using automake,
using libtool would be pretty hellish ...

... but, shouldn't automake be a requirement on a developers machine if,
and only if, they modify either the Makefile.am files *or*
configure.in?  Like, it should only be a requirement for a select few of
the developers?

It will be interesting, no doutb.

The problem was that I was using the aclocal program, which comes with
automake and Tom didn't want to install that. In all truth, it doesn't do
*much* more than cat, so we use that for now.

Just to be perfectly clear: I don't have a problem with installing
automake if we come to an agreement that we need to require it as
a build tool.  I do have a problem with requirements creep happening
without discussion/consensus.  For now, I'd like to see if we can
avoid needing automake...
