[PATCH v2 0/7] hn/reftable "fixes" for BSD

A few issues I noticed while buiding "seen" in some BSD systems.

Patches 1-3 aren't changed from v1, and 4 had the fixes suggested by
Junio[1] added.

Patch 5 affects an EOL NetBSD 7.2 system and therefore might be dropped
but I thought it was safe/generic enough and might become useful in
other old systems as well.

The last 2 patches are a well known recurring issue, that even prompted
a explicit documentation update in cc0c42975a (CodingGuidelines: spell
out post-C89 rules, 2019-07-16).

All these patches are expected to be applied on top of hn/reftable and
hopefully absorved and discarded.
