# Ex skeletal makefile for version 7, USGS Overlay system
#
# NB: This makefile doesn't indicate any dependencies on header files.
#
# Ex is very large - this version will not fit on PDP-11's without overlay
# software.  Things that can be turned off to save
# space include LISPCODE (-l flag, showmatch and lisp options), UCVISUAL
# (visual \ nonsense on upper case only terminals), CHDIR (the undocumented
# chdir command.)  CRYPT includes code to handle the -x option to allow
# encrypted files.  Defining CRYPT drags in most of stdio (from the call
# to getpass) and makes vi about 4k text and 4k data bigger).
# VMUNIX makes ex considerably larger, raising many limits
# and improving speed and simplicity of maintenance.  It is suitable only
# for a VAX or other large machine, and then probably only in a paged system.
#
# Don't define VFORK unless your system has the VFORK system call,
# which is like fork but the two processes have only one data space until the
# child execs. This speeds up ex by saving the memory copy.
#
# If your system expands tabs to 4 spaces you should -DTABS=4 above
#
# Make ex.40 for nonseparate I/D machines without floating point,
# ex.34 for nonseparate I/D machines with floating point,
# and ex.70 if you have separate I/D (and floating point).
# Take a look at ex_tune.h and ex_local.h before compiling.
