## Define MAIL_USE_FLOCK (or LOCKF) if the mailer uses flock (or lockf) to
## interlock access to the mail spool. The alternative is a lock file named
## /usr/spool/mail/$USER.lock.

## On GNU/Linux systems, both methods are used by various mail programs.
## I assume most people are using newer mailers that have heard of flock.
## Change this if you need to.
## Debian contains a patch which says: ``On Debian/GNU/Linux systems,
## configure gets the right answers, and that means *NOT* using flock.
## Using flock is guaranteed to be the wrong thing. See Debian Policy
## for details.'' and then uses `#ifdef DEBIAN'. Unfortunately the
## Debian maintainer hasn't provided a clean fix for Emacs.
## movemail.c will use `maillock' when MAILDIR, HAVE_LIBMAIL and
## HAVE_MAILLOCK_H are defined, so the following appears to be the
## correct logic. -- fx
## We must check for HAVE_LIBLOCKFILE too, as movemail does.
## liblockfile is a Free Software replacement for libmail, used on
## Debian systems and elsewhere. -rfr.
