#
# Ex skeletal makefile for version 7
#
# NB: This makefile doesn't indicate any dependencies on header files.
#
# Ex is very large - it may not fit on PDP-11's depending on the operating
# system and the cflags you turn on. 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.)
#
# 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.
# -DVMUNIX makes an ex which can edit very large files (eg the w2a dictionary)
# this allows 200000 lines and about 16M byte temp files.
#
# If your system expands tabs to 4 spaces you should -DTABS=4 below
#
# Ex is likely to overflow the symbol table in your C compiler.
# It can use -t0 which is (purportedly) a C compiler with a larger
# symbol table.  The -t1 flag to the C compiler is for a C compiler
# which puts switch code in I space, increasing the text space size
# to the benefit of per-user data space.  If you don't have this it
# doesn't matter much. Another method, which works on v7 pdp-11's,
# is to use pcc for ex_io.c instead of cc.
