You're right, I'd forgotten.  Well, it's a real problem but it can
wait until after 2.60 I guess.

Well, now that we're on this subject, I don't understand this
suggestion and I'm not sure I agree with it.  This is partly because
"make update" does not work.  I haven't used it for some time, for
this reason.  Here's an example:

   $ make update
   wget -C off http://www.gnu.org/prep/standards.texi -O  
./doc/standards.texi.t \
     && ./config/move-if-change  ./doc/standards.texi.t  ./doc/standards.texi
   --11:02:20--  http://www.gnu.org/prep/standards.texi
              => `./doc/standards.texi.t'
   Resolving www.gnu.org... 199.232.41.10
   Connecting to www.gnu.org[199.232.41.10]:80... connected.
   HTTP request sent, awaiting response... 404 Not Found
   11:02:20 ERROR 404: Not Found.

   make: *** [get-./doc/standards.texi] Error 1

There are other problems with "make update".  As I recall, "make
update" really needs to be rewritten and in the meantime we shouldn't
recommend it.

Worse, I can't check out the source code from CVS and expect it to
work, even if everything is regenerated properly in CVS.  This sort of
gotcha has to be discouraging potential contributors.  So there is a
real need for a bootstrap procedure, even if we don't have one right
now.

Here's an example failure, from a pristine CVS checkout right now:

You are about to use an experimental version of Autoconf.  Be sure to
read the relevant mailing lists, most importantly <address@hidden>.

Below you will find information on the status of this version of Autoconf.


* Status

                    /*--------------------------.
                    | Sane for full scale use.  |
                    `--------------------------*/

* No known serious or important bugs.

* Minor Problems

Some Makefile segments do not behave correctly in VPATH builds with proprietary
`make' programs.  Some BSD `make's will work.  For best results, build in the
source directory or use GNU `make'.

Parallel builds via `make -jN' do not work.
