* all mallocs now use xmalloc (and so are OOM error safe), and
the common error handling saves a few bytes. Thanks to
Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
* Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.

Hi there.

As a point of reference, here's a slightly tweaked analysis of the
programs on the system I'm reading your mail on. Basically, I ran the
following script...
Q> #!/bin/bash
Q> function use() {
Q> for Z in $* ; do
Q> strings $Z | grep /proc | sed "s=^=$Z ="
Q> done
Q> }
Q> use /{,s}bin/* /usr/{,s}bin/* | sort -u | tee proc-usage
...and then went through it removing comments and print format
strings. Replace /proc with /dev and you'd soon have an equivalent
list for that - although I can report that such is MUCH larger...
There are three programs therein that refer to /proc/mounts ...
/bin/mount
/bin/umount
/usr/bin/eject
...and, as you stated, none that refer to /proc/atm on this system.
However, as this is a RedHat Linux 5.0 based system, that's not
necessarily an up to date reference thereto...
Here's the list anyway...
