# makefile for make Copyright Julian H Stacey @(#) Version 2.2
# This makefile works for both
#	1) berkley unix/make/bourne shell
#	2) msdos with a minix make that has been ported, and command.com.
# Do not change the syntax without checking on both machines.

# JHS exepack stack note
#	If make.exe says Error 2009: Not enough space for environment
#	it may be because you have used too much stack with
#				exemod make.exe -stack f000
#	try instead		exemod make.exe -stack a000
#	-AL : Large model
#	-Os optimise for space
#	-FPi  -FPc -FPa are all float options, all produce the same size 
#		executable, , because there are no floats or doubles in make.c

# phils standard flags: -Ox -FPi -Gs -DMSDOS
# -Ox maximal optimise, relax alias checking, favor code size, remove stack probes
# -FPi in line float instructions + select emulator doesnt need FPchip
# -Gs remove stack probes
