For some of my packages, I use some m4 macros to specify the version 
number.  The top of the pygtk configure.in file looks like the following:

-*- mode: m4 -*-
AC_PREREQ(2.52)

dnl the pygtk version number
m4_define(pygtk_major_version, 1)
m4_define(pygtk_minor_version, 99)
m4_define(pygtk_micro_version, 6)
m4_define(pygtk_version, 
pygtk_major_version.pygtk_minor_version.pygtk_micro_version)

AC_INIT(pygtk, pygtk_version,
       
[http://bugzilla.gnome.org/enter_bug.cgi?product=gnome-python&component=pygtk])

AC_DEFINE(PYGTK_MAJOR_VERSION, pygtk_major_version, [PyGtk major version])
AC_DEFINE(PYGTK_MINOR_VERSION, pygtk_minor_version, [PyGtk minor version])
AC_DEFINE(PYGTK_MICRO_VERSION, pygtk_micro_version, [PyGtk macro version])

AC_CONFIG_SRCDIR([gtk/gtkmodule.c])
AM_CONFIG_HEADER(config.h)

AM_INIT_AUTOMAKE(AC_PACKAGE_NAME, AC_PACKAGE_VERSION)


This way I only list the version number once, and anywhere I want to 
repeat it, I just use "pygtk_version".  I use similar code to list the 
required versions of other packages at the top of the configure.in file, 
so that they are easy to update.  This is straight macro substitution, 
so choose macro names that aren't used in other parts of the script.
