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: NEWPROT use the new protocol, instead of the default protocol
20:
21: V6 Assume the v6 features insted of the v7 ones.
22:
23: FUID use the funny uid's present on Cory and CC
24: ROPTION The local machine mail program has the magic -r option
25: ROPTION2 The local machine mail program has the magic -r option
26:
27: HPASSWD The local machine has the hashed password stuff
28:
29: SPACCT under certain circumstances, allow remote login without acct
30:
31: OLDMAIL mail is in home-directory/.mail
32: USRMAIL mail is in /usr/mail/name
33: (mail is in /usr/spool/mail/name)
34:
35: CC Machine is a Computer Center machine
36: NUID userid (as returned by getuid()) on this machine
37: UID1CHAR Uses vanila Version6 userid's (only 1 byte for uid)
38: NOEUID Does not have the geteuid() system call
39:
40:
41: The conditonal flags are first defined
42: in "/usr/include/whoami.h" on the local machine.
43:
44: For "normal" version 6 machines, there is a dummy machine
45: definition for "VANILLA6" which indicates the v6 UNIX options.
46:
47: For "normal" version 7 machines, there is a dummy machine
48: definition for "VANILLA7" which indicates the v7 UNIX options.
