Then we freeze the code and correct no bugs, because every user exploiting
a bug is potentially the user of a feature.  DBM was abstracted by Greg and
Ryan to avoid *exactly* this problem, long before apr-1.0.0 shipped.

There is nothing in the autodocs suggesting that any dbm or dbd API are
valid apr_util calls.  That is as opposed to the incomplete ldap interface,
which we agree is bogus.

Then vote for [one of] Bojan's patches.  I like the second one better,
having reviewed them both.  We'll undo this mess entirely in 2.0.

Bojan's patch restores the autogunk behavior to 1.3.8-dev quite effectively,
IMHO.  And I'm voting 0 because we disagree on this assessment, but I'm not
holding up improvements of compatibility if others believe that they are,
in fact, improvements.  The patch appears technically correct.

We didn't get any further than this on the db build compatibility issue, right?

(I don't see any commits or further discussion on this issue.)
