#	Makefile for NetHack's utility programs.
#	SCCS Id: @(#)Makefile.utl	3.2	95/05/06

# newer makes predefine $(MAKE) to 'make' and do smarter processing of
# recursive make calls if $(MAKE) is used
# these makes allow $(MAKE) to be overridden by the environment if someone
# wants to (or has to) use something other than the standard make, so we do
# not want to unconditionally set $(MAKE) here
#
# unfortunately, some older makes do not predefine $(MAKE); if you have one of
# these, uncomment the following line
# (you will know that you have one if you get complaints about unable to
# execute things like 'foo.o')
# MAKE = make

# if you are using gcc as your compiler,
#	uncomment the CC definition below if it's not in your environment
# CC = gcc
#
#	For Bull DPX/2 systems at B.O.S. 2.0 or higher use the following:
#
# CC = gcc -ansi -D_BULL_SOURCE -D_XOPEN_SOURCE -D_POSIX_SOURCE
# 
#	If you are using GCC 2.2.2 or higher on a DPX/2, just use:
#
# CC = gcc -ansi
#
# if your make doesn't define a default SHELL properly, you may need
#    the line below (Atari users will need a bourne work-alike)
# SHELL = /bin/sh
