# 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
#
#	For HP/UX 10.20 with GCC:
# CC = gcc -D_POSIX_SOURCE
#
# 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
# for Atari
# SHELL=E:/GEMINI2/MUPFEL.TTP

# flags may have to be changed as required
# flags for 286 Xenix:

# CFLAGS = -DDUMB -Ml -I../include

# CFLAGS = -DAPOLLO -O -I../include

# flags for AIX 3.1 cc on IBM RS/6000 to define
# a suitable subset of standard libraries
# (note that there is more info regarding the "-qchars=signed"
# switch in file Install.unx note 8)
# CFLAGS = -D_NO_PROTO -D_XOPEN_SOURCE -O -I../include -qchars=signed
# and for AIX 3.2:
# CFLAGS = -D_NO_PROTO -D_XOPEN_SOURCE -D_ALL_SOURCE -O -I../include -qchars=signed

# flags for A/UX 2.01 using native cc or c89
# gcc predefines AUX so that's not needed there
# CFLAGS = -ZS -D_POSIX_SOURCE -O -I../include -DAUX

# flags for IRIX 4.0.x using native cc
# SGI cc 3.10 will fail to compile makedefs with -O
# CFLAGS = -I../include -D__STDC__ -woff 100,293

# flags for Linux
#   compile normally
# CFLAGS = -O2 -fomit-frame-pointer -I../include
# LFLAGS = -L/usr/X11R6/lib
#   OR compile backwards compatible a.out format
# CFLAGS = -O2 -b i486-linuxaout -fomit-frame-pointer -I../include
# LFLAGS = -b i486-linuxaout -L/usr/X11R6/lib

# flags for BeOS using the command line

# If you are cross-compiling, you must use this:
OBJDIR = .
# otherwise, you can save a little bit of disk space with this:
#OBJDIR = ../src

# if you change this to 1, feedback while building will omit -Dthis -Wthat
# -Isomewhere so that each file being compiled is listed on one short line;
# it requires support for '$<' in rules with more than one prerequisite
# (rather than just in suffix default rule), such as is implemented by
# gnu make and others which have picked up its extensions;
# allowed values are 0, 1, and empty (which behaves like 0)

# TODO? the link/load commands below are handled differently from the ones
# in Makefile.src; these use '$(CC) $(LFLAGS)' and ought to be changed to use
