Thank you for your help, and your offer to help with particular code. I
think I will put this project on the backburner until I am hit with a
desire to learn the depths of gnu build tools and M4 as the project has
issues many warnings (including one about improperly quoted arguments),
and gnu build tools is something I would like to learn at some point.
However, if out of curiosity you wish to duplicate the bug, here are the
steps:
download the debian copy of the lincity sources from
http://deb.debian.org/debian/pool/main/l/lincity/lincity_1.13.1.orig.tar.gz
unpack and cd into the folder.
run `autoupdate`
run `autoconf`
then run `./configure`
and it generates the corresponding error. a log of me doing this is found
in lincity-autoconf-bug-clean.txt
As for building autoconf, it turns out that `./bootstrap -v` only fails if
I do a shallow clone of the repository. I clearly don't know enough git,
as I assumed shallow clones would always be safe. Attached is the unedited
output of `./bootstrap -v &> /tmp/autoconf-shallow-failure.txt` for the
shallow clone. If I do a full clone then I get no failures, and it is
included for comparison. The shallow clone was made with `git clone
git://git.sv.gnu.org/autoconf --depth 1`.

I tried to reproduce this problem and could not. When I run autoconf on
a simple configure.ac that uses one of the two macros that trigger the

AC_INIT([demo], [1.0])
AC_HEADER_STDC

AC_INIT([demo], [1.0])
AC_STDC_HEADERS

the resulting configure script does not have the above message embedded
in it at all, and it's syntactically well formed. Autoconf does print a
warning message:

configure.ac:2: You should run autoupdate.

If I then run autoupdate as suggested, what I get is this (same in both cases):

Running autoconf on _this_ prints the warning message about STDC_HEADERS
but the resulting configure script, again, doesn't embed the warning message
and it runs fine.

Ok, so that *probably* means it's being sloppy about M4 quotation and that's
*probably* the problem. M4 quotation errors can easily cause bizarre syntax
errors like this in the generated configure script, and, unfortunately,
autoupdate cannot correct those errors. I advise you to read through all
the subsections of
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.72/html_node/M4-Quotation.html
(it says "autoconf users can skip this" at the top but that's wrong)
and then try to edit your old configure.ac (or possibly it's so old that
it's named configure.in?) to quote things more carefully, and see if that
makes the problem go away.
If you can show me your very old code base (just a URL for a source code
repository is fine), I may be able to give more specific advice.
I considered trying my hand at writing a patch, but following the
instructions in README-hacking and executing ./bootstrap confusingly gives
me the error that an autoconf version 2.69 or higher is required, despite
my system version being 2.72 and README-hacking suggesting that I
shouldn't need autoconf installed already at all.
Indeed, you should not. You need *automake* installed, but not autoconf.
This is what I see when I run `./bootstrap -v` in a fresh git checkout of
autoconf:

(right after cloning it) and send us the complete and unedited output?
