# Bump sntp_configure_cache_version for each change to configure.ac or
# .m4 files which invalidates cached values from previous configure 
# runs.
#
# If the change affects cache variables used only by the main NTP
# configure.ac, then only its version number should be bumped, while
# the subdir configure.ac version numbers should be unchanged.  The
# same is true for a test/variable that is used only by one subdir
# being changed incompatibly; only that subdir's cache version needs
# bumping.
#
# If a change affects variables shared by all NTP configure scripts,
# please bump the version numbers of each.  If you are not sure, the
# safe choice is to bump all on any cache-invalidating change.
#
# In order to avoid the risk of version stamp collision between -stable
# and -dev branches, do not simply increment the version, instead use
# the date YYYYMMDD optionally with -HHMM if there is more than one
# bump in a day.
