You sound a little frustrated.  I hope I'm not causing that.

But I like the suggestion of adding this in NEWS.Debian.  I just
did so.  Here is what I put in it.  If you have suggestions for
improvement, please pass them along.

NEWS for Debian packaging of Autoconf
This is the Debian packaged version of a CVS snapshot of Autoconf.  It
is close to what will ultimately be Autoconf 2.60.  I have introduced
it into Debian in pre-release to try to help upstream ferret out bugs
in advance.

This CVS snapshot should be largely compatible with older Autoconf
releases back to 2.50, and especially with 2.59.  Please read NEWS for

Two changes bear especial emphasis.  First, quoting from the upstream

** Directory variables adjusted to recent changes in the GNU Coding Standards.
  The following directory variables are new:

    datarootdir   read-only architecture-independent data root [PREFIX/share]
    localedir     locale-specific message catalogs [DATAROOTDIR/locale]
    docdir        documentation root [DATAROOTDIR/doc/PACKAGE]
    htmldir       html documentation [DOCDIR]
    dvidir        dvi documentation [DOCDIR]
    pdfdir        pdf documentation [DOCDIR]
    psdir         ps documentation [DOCDIR]

  The following variables have new default values:

    datadir       read-only architecture-independent data [DATAROOTDIR]
    infodir       info documentation [DATAROOTDIR/info]
    mandir        man documentation [DATAROOTDIR/man]

  This means that if you use any of address@hidden@', address@hidden@', or
  address@hidden@' in a file, you will have to ensure `${datarootdir}' is
  defined in this file.  As a temporary measure, if any of those are
  found but no mention of `datarootdir', the substitutions will be
  replaced with values that do not contain `${datarootdir}', and a
  warning will be issued.

This has proven to be a problem in some cases where the advice in the
manual is not followed.  Please refer to the "Defining Directories"
node in the manual, titled "How do I `#define' Installation
Directories?", for more details.  (The manual can be obtained by
installing the "autoconf-doc" package from the non-free distribution
that accompanies Debian.)

Here is a second item that bears mention, again from upstream NEWS:

  No longer automatically arrange to declare the 'exit' function of C,
  when a C++ compiler is used.  Standard Autoconf macros no longer use
  'exit', so this is no longer an issue for them.  If you use C++, and
  want to call 'exit', you'll have to arrange for its declaration
  yourself.  But we now suggest you return from 'main' instead.
