# Makefile for tn3270 and friends...
# @(#)makefile	3.1  10/29/86
#
#	This is the makefile for tn3270.  Note that we use ../telnet.c
# (compiled with special options; see below) to provide the telnet
# support we need.
#
#	The following are the defines that may be passed (via the cc
# -D option) to the compiler.
#
#	The first group relate only to ../telnet.c:
#
#	TN3270		- 	This is to be linked with tn3270.  Necessary
#				for creating tn3270.
#
#	DEBUG		-	Allow for some extra debugging operations.
#
#	NOT43		-	Allows the program to compile and run on
#				a 4.2BSD system.
#
#	PUTCHAR		-	Within tn3270, on a NOT43 system,
#				allows the use of the 4.3 curses
#				(greater speed updating the screen).
#				You need the 4.3 curses for this to work.
#
#	FD_SETSIZE	-	On whichever system, if this isn't defined,
#				we patch over the FD_SET, etc., macros with
#				some homebrewed ones.
#
#	SO_OOBINLINE	-	This is a socket option which we would like
#				to set to allow TCP urgent data to come
#				to us "inline".  This is NECESSARY for
#				CORRECT operation, and desireable for
#				simpler operation.
#
#	LNOFLSH		-	Detects the presence of the LNOFLSH bit
#				in the tty structure.
#
#
#	Here are some which are used throughout the system:
#
#	SLOWSCREEN	-	If SLOWSCREEN is defined, we generate code
#				that attempts to optimize the line between
#				the computer (on which tn3270 runs) and the
#				user's terminal (which line may be 1200 baud,
#				or some such) at the cost of CPU time on
#				the above referenced computer.
#
#	unix		-	Compiles in unix specific stuff.
#
#	msdos		-	Compiles in msdos specific stuff.
