#
# Non-standard object files require special non-posix features be available in 
# order to compile and link.  NSTCFLAGS are flags to the compiler to make 
# non-posix symbols and features available.  
#
# Here are the problem areas in porting to new machines:
#
#    log.c:   vsprintf must return an int.  If it doesn't, you have a
#             non-ANSI machine.  It also needs ANSI's stdarg.h.
#             The default source should work, since it tries to detect these.
#             openlog doesn't return a value on some BSD machines.
#    tty.c:   If you don't have POSIX termios, you're hosed.  This code is
#             completely POSIX except:  The flag ONLCR is not part of POSIX.  
#             Some machines require an ioctl to acquire the controlling terminal
#             for the session leader.  See the function mkCtrlTty.
#   txfr.c:   depends heavily upon the BSD select(2) semantics, which are
#             only vaguely documented.  If the code runs incorrectly here, 
#             it's a bitch to diagnose and fix.
#  socket.c:  Networking isn't POSIX yet.  This isolates all networking calls.
#  posignal.h: The arguments to a signal handler are machine-specific.
#     pty.c:  Many newer POSIX style machines do pty stuff completely
#             differently from eachother. I've had to hack this a bit.
#
# If any of the above files fail to compile, it's most likely because the
# header files on your system require a compilation option to make non-posix
# symbols visible.  For example, <sys/types.h> declares u_short which is
# required to compile socket.c.  To get around this problem, I've not defined
# _POSIX_SOURCE until *after* <sys/types.h> and <sys/time.h> are included,
# which "fixes" the problem on most machines.  For the ONLCR problem, 
# grep for "ONLCR" in /usr/include{/sys}/termio*.h.  Once you find that 
# symbol, look for an #ifdef to enable it and add that flag to NSTCFLAGS
# in this Makefile.
#
# Make *SURE* to enable the compile options to not use shared libraries or
# run-time procedure binding because it enables a serious trojan horse.
# Many vendors enable dynmaic binding by default; so be careful.
#
# The include files and source is constructed to make it easy to change some 
# of the default source in this makefile rather than hacking on the C source 
# directly.  This will make your life easier when new releases come out.
# Just add a "-D<name>=<value>" to LOGINDFLAGS below.  For example see 
# the -DLOG_FILE=...below.  All these values have suitable defaults.  You 
# don't need to touch them unless you want to or I've set them incorrectly by 
# default.
#
# deslogin.h:
#    SETUP_TIMEOUT	ms for login sequence handshake
#    LOGIN_TIMEOUT	seconds to wait for passphrase response
#    INACTIVITY_TIMEOUT	seconds of no I/O activity before terminationg session
#    DESLOGIN_PORT	"Well-known" Port to post listen to for deslogind
#    SERVICE_NAME	The name of the deslogin service in /etc/services
#    LOGIN_PROG		Full pathname of login program for -w option
#
# deslogind.c:
#    DEFAULT_UMASK	Passed to umask(2) upon login.
#    TTY_MODE		Permissions for controlling terminal slave pty device
#    USERPATH		Default path
#    SYSTEMPATH		Default path for user id 0.
#    DEFAULT_TERM	What to set the TERM envt variable to.
#    USER_FILE		Path of file containing passphrase username pairs
#    NOLOGIN_FILE	File which denies all logins containing denial message
#    LOG_FILE		Where to output all logging messages
#
# txfr.c:
#    WRITE_RETRY_TIME	ms timeout for EAGAIN error on write attempt
#

# Don't change anything below this line unless you are porting to a new
# incompatable platform and the existing configuration fails to work.
