I think there wasn't any.  [I was fairly sure the configurey worked at
one stage, but that was perhaps a couple of years back and it seems
the current version doesn't DTRT despite what the Debian patch says.]

It's normal autoconf for `can link -lmail'.

I think movemail is written to work with function `maillock' (?) from
a proprietary libmail.  Debian has the same function in liblockfile.
Defining HAVE_LIBMAIL (albeit a lie) gets movemail to use maillock --
as I commented in gnu-linux.h -- without touching movemail.c.  See
conditionals on HAVE_LIBMAIL &c near the top of movemail.c.

Is that clear?
