Agreed.

Attached is a patch that replaces src/port/{strtol.c,strtoul.c} with
versions derived from current NetBSD CVS sources, which has a 3-clause
BSD license. The code is different than the FreeBSD sources in a few
ways (mostly trivial); I've eyeballed the diffs and I couldn't see
anything that would result in a change in behavior, but I may have
missed something. The NetBSD sources are actually better in a few ways
(e.g. they don't use the "register" keyword).

Barring any objections, I intend to apply this patch to HEAD on Tuesday.

There are a few more files whose licenses need updating, but I'll leave
that for later. And of course, there's contrib/ to sort out as well...
