-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Jim Meyering on 11/2/2007 1:01 PM: >> Also, why is the current version something like 2.61a-248-dc51? >> That compares wrongly in order with 2.61b which is what post 2.61a >> CVS versions had. > > Because these versions are post-2.61a, and pre-2.61b :-) Hmm. Maybe it's time to rewrite m4_version_compare to treat `-' the same as `.' when it occurs in the original version strings. Currently, m4_version_unletter (a key component in AC_PREREQ) interprets the - in the string as a subtraction, with the following results: m4_version_unletter([2.61b]) => 2.62.-1.11 m4_version_unletter([2.61a-248-dc51]) => 2.62.-1.-239.-1.622261 Side-by-side, this correctly compares 61a-nnn as smaller than 61b. However, for increasing nnn, the further you get from 61a, the more negative the result gets, which is the wrong direction. I'll throw together a patch when I have more time. - -- Don't work too hard, make some time for fun as well!
