Smail 3.1 and SCO UNIX 3.2.2

[Chip Salzenberg]

According to graham at netwrx1.NW1.COM (James M. Graham):
>Has anyone built Smail 3.1 on SCO UNIX/386 Release 3.2.2? If so, did you
>have to make changes to the source or were you able to build it via the
>EDITME definitions alone?

It needed its own configuration file.  The SCO Unix 3.2.0 rename()
call is broken, so we avoid it.  So you have to change the Smail
rename() function to take "const char *" instead of "char *"
parameters, for compatibility with system headers.

Here is my config file from the conf/os directory.

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."

X# LOCKING_PROTOCOL - macros for efficient file locking
X#
X# Define macros for performing high-performance locking on files
X# These should include the following macros:
X#
X#	lock_fd		- given a file descriptor, either lock the
X#			  file for exclusive access without blocking
X#			  and return SUCCEED or fail to lock and
X#			  return FAIL.  This is used for locking spool
X#			  files.
X#
X#	lock_fd_wait	- given a file descriptor, lock it for
X#			  exclusive access and return SUCCEED or
X#			  return FAIL.  Blocking is permitted.  This
X#			  may be used for locking mailbox files.
X#
X#	unlock_fd	- given the file descriptor of a file locked
X#			  with the lock_fd macro, unlock that file.
X#			  This can be an expression cast to void.
X#
X#	unlock_fd_wait	- given the file descriptor of a file locked
X#			  with the lock_fd_wait macro, unlock that
X#			  file.  This can be an expression cast to
X#			  void.
X#
X#	lock_fd_rd_wait	- given a file descriptor, lock it for shared
X#			  access.  Blocking is permitted.  This is
X#			  used when reading forward files or mailing
X#			  list files.  Closing the file shoud be
X#			  sufficient for releasing the lock.  This
X#			  should return SUCCEED or FAIL.
X#
X# If no reasonable high-efficiency locking method is available for
X# your system, then do not define this macro, or set it to a null
X# string.
X#
X# If the locking protocol requires that the file being locked be
X# writable, define LOCK_REQUIRES_WRITE.
X#
X# To use the System V shared lock fcntl(), define USE_FCNTL_RD_LOCK,
X# and define lock_fd_rd_wait() to be (fcntl_rd_lock(fd)), and declare
X# fcntl_rd_lock() to be extern int.
X
XLOCKING_PROTOCOL="\

X# to be "yes", otherwise it should not be defined.

X# FLOCK_MAILBOX - should mailbox files be locked with lock_fd_wait

X# mail user agents.  Otherwise, do not set this.

X# Normally this is either /usr/spool/mail for a V7/BSD-derived system

X# This pathname is used as a last resort in writing panic messages from
X# smail.  Normally, it is /dev/console.

X# declared using the C code below:
X#
X#	strcat(s1,s2)	- concatenate string s2 onto the end of s1
X#	strncat(s1,s2,n)- concatenate s2 onto s1 with length constraint n
X#	strcmp(s1,s2)	- compare strings s1 and s2
X#	strncmp(s1,s2,n)- compare s1 and s2 with length constraint n
X#	strcpy(s1,s2)	- copy string s2 to s1

X#	index(s,c)	- point to first occurance of c in string s
X#	rindex(s,c)	- point to last occurance of c in string s
X#	bzero(b,n)	- zero n bytes starting at location b
X#	bcopy(b1,b2,n)	- copy b1 to b2 for n bytes
