Rather than reading it dynamically from the ChangeLog -- that, remember, is only a dummy in a Git checkout! To avoid risking the definition to get out-of-sync, let's enhance the maintainer target 'update-copyright' to update it automatically (the same way it's done in the Automake build system). * configure.ac (RELEASE_YEAR): New AC_SUBST'd variable. * cfg.mk (update-release-year): New maintainer-specific target to automatically update the value of that variable. (update-copyright): Depend on the new target. * bin/local.mk (RELEASE_YEAR): Drop definition. (edit): Simplify quoting of $(RELEASE_YEAR). * lib/Makefile.am (RELEASE_YEAR): Drop definition. (m4sugar/version.m4): Simplify quoting of $(RELEASE_YEAR). Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
