5: *** Pre-processor Flags ***
6:
7: This set of code is controlled by this set of conditional
8: compilation flags:
9:
10: TESTING if defined, do not generate tests, etc. which require
11: super-user status.
12:
13: OLDTTY if defined, compile for old 1 character TTY names
14: CCTTY if defined, compile for CC tty name format
15: if neither is defined, use v7 ttyname format
16:
17: PASSWDF compile in code to handle /etc/passwdf - split passwd files
18:
19: V6 Assume the v6 features instead of the v7 ones.
20:
21: FUID use the funny uid's present on CC V6
22:
23: DELIVERM Uses the delivermail program
24:
25: HPASSWD The local machine has the hashed password stuff
26:
27: OLDMAIL mail is in home-directory/.mail
28: USRMAIL mail is in /usr/mail/name
29: (mail is in /usr/spool/mail/name)
30:
31: CC Machine is a Computer Center machine
32: NUID userid (as returned by getuid()) on this machine
33: UID1CHAR Uses vanila Version6 userid's (only 1 byte for uid)
34: NOEUID Does not have the geteuid() system call
35: NFREECMD doesn't allow any "network" free commands
36: NOFP floating point just doesn't work on this machine
37: NOREMACCT allows remote printing without an account
38:
39:
40: The conditonal flags are first defined
41: in "/usr/include/whoami.h" on the local machine.
42:
43: For "normal" version 6 machines, there is a dummy machine
44: definition for "VANILLA6" which indicates the v6 UNIX options.
45:
46: For "normal" version 7 machines, there is a dummy machine
47: definition for "VANILLA7" which indicates the v7 UNIX options.
48: (VM/UNIX and Berkeley VM/VAX/UNIX can use this)
