The process group code needs a patch. The next-to-last patch below
fixes job control in shell buffers - perhaps that will help you. If
not please let me know! Rich
To build emacs 19.16 apply the patches below and type:
configure i386-free-386bsd --with-x11 --x-includes=/usr/X386/include --x-libraries=/usr/X386/lib --prefix=/usr/gnu
make
The first two patches resolve conflicts in the declaration of
getpwuid().

If your libc has been modified to call things like abort(), etc.,
which are in gnulib, you must add gnulib last on the command line when
linking temacs.

The patch below makes ^C work in shell buffers (i.e. job control for
sub-processes).

The following patch fixes the time-of-day display. If you compile
without this patch and change /etc/localtime, the emacs binary will
display the time in the old timezone rather than recognize the change.
