This is what I want:

http://www.gnu.org/software/ac-archive/Miscellaneous/ac_define_dir.html

However, it does not seem to work on my system (Debian Woody,
up-to-date, with autoconf and automake drawn in from Sid). 

The output I get from running my bootstrap script is:
+ aclocal
+ autoheader
autoheader2.50: missing template: DATADIR
+ exit 1

The bootstrap script looks thus:
#!/bin/sh
set -x
aclocal && autoheader || exit 1
automake --add-missing --foreign || exit 1
autoconf --warnings=all || exit 1

In case it is interesting, to anyone, here's my configure.in (don't
laugh, I am still trying to learn this stuff... ;)


dnl Process this file with autoconf to produce a configure script.
AC_INIT(pac, 0.2.1, stig at brautaset.org)
AC_CONFIG_SRCDIR(src/pac.c)		dnl my sources are here
AC_CONFIG_AUX_DIR(config)		dnl install-sh etc stored here

AM_CONFIG_HEADER(config/config.h)	dnl the name of the header file
AM_INIT_AUTOMAKE			dnl needs to come after above cruft
AM_MAINTAINER_MODE			dnl I'm a power user ;)

# Checks for programs.
AC_PROG_AWK
AC_PROG_CC

AC_DEFINE_DIR(DATADIR, $datadir)

# header files
AC_HEADER_STDC

Puh, that should be all, I think..
