# @(#)makefile	2.3 1/16/96
# the following can be added to CFLAGS for various things
#
# add -DNOVOID		If your compiler can not handle the void keyword.
# add -DBSD		For BSD4.[23] UNIX Systems.
# add -DDOS		For MS-DOS/PC-DOS Systems, Micro-Soft C 4.0, Turbo C
#				Use the ANSI option.
# add -DNOGETOPT	If your library doesn't have getopt().
#				Another routine will be used in its place.
# add -DNOVARARGS	If you have neither <stdarg.h> (ANSI C) or
#				<varargs.h> (pre-ANSI C).
#				Another method will be compiled instead.
# add -Ddodebug		To compile in debugging trace statements.
# add -Ddoyydebug	To compile in yacc trace statements.
#
# add -DUSE_READLINE	To compile in support for the GNU readline library.
