# Automake 1.10.3 and 1.11.1 fix a security flaw discussed here:
#
#   http://thread.gmane.org/gmane.comp.sysutils.autotools.announce/131
#
# To avoid 1.11, we make 1.11.1 the minimum version.
#
# We want gnits strictness only when rolling a stable release.  For
# release candidates, we use version strings like 2.4.3_rc1, but gnits
# doesn't like that, so we let the underscore disable gnits.  Between
# releases, we want to be able run make dist without being required to
# add a bogus NEWS entry.  In that case, the version string
# automatically contains a dash, which we also let disable gnits.
