?X: from config.sh have been loaded, so that we can supersede them.

?MAKE:cf_time cf_by: date Oldconfig
?MAKE:	-pick add $@ %<
?S:cf_time:
?S:	Holds the output of the "date" command when the configuration file was
?S:	produced. This is used to tag both config.sh and config_h.SH.
?S:.
?S:cf_by:
?S:	Login name of the person who ran the Configure script and answered the
?S:	questions. This is used to tag both config.sh and config_h.SH.

?LINT:change LC_ALL LANGUAGE
: who configured the system
?X: Ensure English date -- Jarkko Hietaniemi
cf_time=`LC_ALL=C; LANGUAGE=C; export LC_ALL; export LANGUAGE; $date 2>&1`
?X:
?X: Leave a white space between first two '(' for ksh. The sub-shell is needed
?X: on some machines to avoid the error message when logname is not found; e.g.
?X: on SUN-OS 3.2, (logname || whoami) would not execute whoami if logname was
?X: not found. Sigh!
?X:
?X: Convex had a broken logname executable which returned a non-zero status,
?X: and that broke the previous:
?X:   cf_by=`( (logname) 2>/dev/null || whoami) 2>&1`
?X: Switch to emergency mode... -- RAM, 19/04/94
?X:
?X: Parentheses needed to avoid error message if the program does not exist.
?X: Uses case instead of $test so it can be put before $test is defined.
?X: Don't redirect to a file because on Ultrix (under script?) logname
?X: outputs a blank line first.  This method will apparently work.
