# We check this every time make is run, with configure.ac being touched to
# trigger an update of the build system files if update_version changes the
# current PACKAGE_VERSION (or if package_version was modified manually by a
# user with either AUTO_UPDATE=no or no update_version script present - the
# latter being the normal case for tarball releases).
#
# We can't just add the package_version file to CONFIGURE_DEPENDENCIES since
# simply running autoconf will not actually regenerate configure for us when
# the content of that file changes (due to autoconf dependency checking not
# knowing about that without us creating yet another file for it to include).
#
# The MAKECMDGOALS check is a gnu-make'ism, but will degrade 'gracefully' for
# makes that don't support it.  The only loss of functionality is not forcing
# an update of package_version for `make dist` if AUTO_UPDATE=no, but that is
# unlikely to be a real problem for any real user.
