20211554Srpaulo# If the change affects cache variables used only by the main NTP
21211554Srpaulo# configure.ac, then only its version number should be bumped, while
22211554Srpaulo# the subdir configure.ac version numbers should be unchanged.  The
23211554Srpaulo# same is true for a test/variable that is used only by one subdir
24211554Srpaulo# being changed incompatibly; only that subdir's cache version needs
25211554Srpaulo# bumping.
26211554Srpaulo#
27211554Srpaulo# If a change affects variables shared by all NTP configure scripts,
28211554Srpaulo# please bump the version numbers of each.  If you are not sure, the
29211554Srpaulo# safe choice is to bump all on any cache-invalidating change.
