# Below find *fragments* of how to augment this makefile for other systems.
# Note that I simply collected all definitions I am currently aware of,
# but that this collection is still subject to change.
#
# You are welcome to improve it!
#
# Note also that most of the systems listed below are already supported
# by special makefiles, though I'd like to make these obsolete by a
# future version of this file. Currently, use the special makefile!
#
# I could not test the settings below, lacking a well-behaved DOS make.exe:
# DOS/DJGPP + DJ previewer		# Use dosdjgpp.mak !
#
# DEFINES   = -DDOS -DGNU -DHAS_DOS_DJGR
# PREVIEWER = to_dj_gr
# ALL_LIBS  = -lgr -lm
# BINDCMD   = copy /b c:\djgpp\bin\stub.exe+$(PROGRAM) $(PROGRAM).exe
#
# DOS / Borland bcc			# Use borland.mak !
#
# DEFINES   = -DDOS -DHAS_DOS_VGA
# PREVIEWER = to_vga
# ALL_LIBS  = -lm
#
# ATARI ST/TT
#
# DEFINES   = -DATARI			# Use atari.mak !
# PREVIEWER = to_atari
# ALL_LIBS  = -lm 	# Add whatever may be needed for Ataris
#
# AMIGA

# DEFINES   = -DAMIGA			# Use amiga.mak !
