*** Pre-processor Flags ***

This set of code is controlled by this set of conditional
compilation flags:

TESTING		if defined, do not generate tests, etc. which require
		super-user status.

OLDTTY		if defined, compile for old 1 character TTY names
CCTTY		if defined, compile for CC tty name format
		if neither is defined, use v7 ttyname format

PASSWDF		compile in code to handle /etc/passwdf - split passwd files

V6		Assume the v6 features instead of the v7 ones.

FUID		use the funny uid's present on CC V6

SENDMAIL	Uses the sendmail program

HPASSWD		The local machine has the hashed password stuff

OLDMAIL		mail is in home-directory/.mail
USRMAIL		mail is in /usr/mail/name
		(mail is in /usr/spool/mail/name)

CC		Machine is a Computer Center machine
NUID		userid (as returned by getuid()) on this machine
UID1CHAR	Uses vanila Version6 userid's (only 1 byte for uid)
NOEUID		Does not have the geteuid() system call
NFREECMD	doesn't allow any "network" free commands
NOFP		floating point just doesn't work on this machine
NOREMACCT	allows netlpr's on remote machines without an account
CSH		use the /bin/csh shell (Paths.h sets BINSH to this path ).
CRN		CC crn's are passed
DONTHOLDBIG	large (size > MAXDAYFILE ) jobs wont be held until night for
		transmission

SWAB		this machine has byte-ordering reversed from the DEC VAX 
		and PDP-11 standard (the only current example is Onyx)
The conditonal flags are first defined
in "local.h" in this directory.

For "normal" version 6 machines, there is a dummy machine
definition for "VANILLA6" which indicates the v6 UNIX options.

For "normal" version 7 machines, there is a dummy machine
definition for "VANILLA7" which indicates the v7 UNIX options.
(VM/UNIX and Berkeley VM/VAX/UNIX can use this)
