Hi all,
utmp.h has been removed from FreeBSD 9.0-CURRENT. This means Emacs from
trunk can no longer build on FreeBSD 9.X or newer because src/filelock.c
tries to include <utmp.h>.
The filelock.c code uses the sysctl interface in FreeBSD, so we don't
really need utmp.h to have a working Emacs version. So I patched
configure.in to check for availability of utmp.h and then filelock.c to
use HAVE_UTMP_H around the include statement.
This seems to work fine, but before updating the packages of Emacs on
FreeBSD I thought I'd ask: does this seem like a reasonable fix? Should
we patch the Emacs trunk too?
The following patch should apply cleanly on the bzr-trunk of Emacs at
revision lekktu@gmail.com-20100118044436-c8dozy11mbqky3qh
Then 'configure' has to be regenerated too, and we should be set :-)

After running a patched Emacs build or a couple of days, I've submitted
the patch below to the editors/emacs and editors/emacs-devel packages of
FreeBSD. Since it's a good idea to keep the "local patches" as small
and few as possible, does anyone from the list feel like pushing this to
the bzr branch for the next pretest too?
Regards,
Giorgos
