35 | # Automake 1.10.3 and 1.11.1 fix a security flaw discussed here: | |
36 | # | |
37 | # http://thread.gmane.org/gmane.comp.sysutils.autotools.announce/131 | |
38 | # | |
39 | # To avoid 1.11, we make 1.11.1 the minimum version. | |
40 | # | |
41 | # We want gnits strictness only when rolling a stable release. For | |
42 | # release candidates, we use version strings like 2.4.3_rc1, but gnits | |
43 | # doesn't like that, so we let the underscore disable gnits. Between | |
44 | # releases, we want to be able run make dist without being required to | |
45 | # add a bogus NEWS entry. In that case, the version string | |
46 | # automatically contains a dash, which we also let disable gnits. | |
