#
# All of the following settings are quite recommended, so you should only
# change them if it becomes really necessary.
#
# Remove -DMB to build without multibyte character support. This will be
#     necessary if the compiler complains about a missing wchar.h, wctype.h,
#     mbtowc(), mbrtowc(), btowc(), wcwidth() etc. You will likely also have
#     to use the old regular expression code in these cases (see below).
# Remove -DBIT8 to get a 7bit-only ex. This setting is mostly provided for
#     testing the internationalization code against the older version and
#     should not normally be removed.
# Add -DNO_BE_BACKSLASH to make backslash a regular character inside RE
#     bracket expressions. This is required for POSIX conformance but
#     conflicts with historical practice for ex.
#
# Some historic comments:
#
# 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), CHDIR (the 
# previously undocumented chdir command.)
#
# If your system expands tabs to 4 spaces you should -DTABS=4 below
#
FEATURES	= -DLISPCODE -DCHDIR -DFASTTAG -DUCVISUAL -DMB -DBIT8

#
# This disables the LC_CTYPE locale settings and assumes all characters
# upwards from octal 0240 are printable ones, like in ISO 8859-1. It
# should only be used if the system's locales are broken. It cannot be
# used in combination with -DMB.
#
#CHARSET	= -DISO8859_1

#
# If you want LC_MESSAGES support using catgets(), define this. To make
# any practical use of it, you also have to create a message catalogue,
# put it in a proper location and change UNKNOWN to its name. See your
# system's documentation on "gencat" or on language support in general
# for further information. This setting is not interesting at the current
# time unless you want to contribute internationalized message catalogues.
#
#LANGMSG		= -DLANGMSG -DCATNAME='"UNKNOWN"'

#
# For POSIX regular expressions, e.g. the star applied to subexpressions
# as in \(ab\)* and localized regular expressions like [:class:], [.c.],
# and [=c=], you need Caldera's 'UNIX(R) Regular Expression Library' or
# the included derivative of it.
#
# Comment out the three following lines if you do not have it or if it
# does not compile; it needs some advanced multibyte character support
# (wchar.h, wctype.h, btowc() etc.) which is not provided by older
# compilation environments.
#
#REINC	= -I./libuxre -DUXRE
#RELIB	= -L./libuxre -luxre
#RETGT	= uxre

#
# VMUNIX should be correct for any modern Unix.
#
# Historic comments:
#
# 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.
#
#      Note by Gunnar Ritter: vfork() is unreliable and one of the worst
#      hacks in Unix history. Do not define VFORK unless you have a
#      special good reason for that.
#
OSTYPE	= -DVMUNIX

#
# On VMUNIX systems, ex can normally edit files up to 32 MB of size. LARGEF
# raises this limit to around 1 GB, but ex will consume much more of core
# and temp file space then.
#
#LARGEF	= -DLARGEF

# 
# The next setting is a crucial one since it determines the way ex
# gets its knowledge about the terminal's capabilities. If you get
# weird results, try using another library here. Uncomment exactly
# one entry.
#
# On System V, the terminfo library may be more accurate than the termcap
# file. To use it, link against the curses library.
#
#TERMLIB	= curses
#
# You may also get terminfo access by using the ncurses library.
#
#TERMLIB	= ncurses
#
# The preferred choice for ex on Linux distributions, other systems that
# provide a good termcap file, or when setting the TERMCAP environment
# variable is deemed sufficient, is the included 2.11BSD termcap library.
#
TERMLIB	= ncurses

#
# Since ex uses sbrk() internally, a conflict with the libc's version of
# malloc() must be avoided. There are two ways to work around this problem.
# The first is to allocate a static pool for all malloc purposes. This will
# work on any kind of system.
#
#MALLOC=malloc.o
#
# If mmap() can be used to allocate anonymous memory, this is the preferred
# choice as it allows to grow memory dynamically as it is needed. This will
# usually work unless you are compiling for a vector machine or another
# unusual enviroment.
MALLOC=mapmalloc.o
