mach.h -- define machine-dependent things
*** 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
DELIVERM Uses the delivermail 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 remote printing without an account
The conditonal flags are first defined
in "/usr/include/whoami.h" on the local machine.
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)
