More to the point, this patch uses the same regex that sed.c is already using
(opportunity to suck in less library code), and even building a dynamically
linked busybox with just expr the result is a slightly smaller binary (by 94
bytes, I dunno what nm --size-sort has to say about it because I didn't build
with debug info, since that changes the binary size a lot by disabling
optimization...)
Your mileage may vary. Handle with caution. Do not taunt happy fun ball.
If we exec /proc/self/exe and only fall back to /bin/busybox if /proc isn't
there, then we have a reasonable chance of having the standalone shell work
even if busybox isn't installed in /bin on the system in question.
Still won't work in a chroot environment, but it's an improvement.
I found that lsmod in busybox does not support linux-2.6.
I fix this issue(it is caused by changes of /proc/modules format).
If you use lsmod in busybox with kernel-2.6, please use this patch.
To: busybox@mail.codepoet.org
Wrap sockaddr_in6 in a ifdef CONFIG_FEATURE_IPV6.
Include sys/types.h instead of asm/types.h.
Include netinet/if_ether.h instead of linux/if_ether.h
The ioctl request argument is an int, not an unsigned short.

BTW: I've ripped out a lot of debug code and changed c++ // comments to /* */
as both were rather confusing for a newbie like me. ;-)
Sorry to the author for that.
I know that this makes mantaining the code easier, but I'm simple minded....

Comments from Vladimir Oleynik influenced the final patch, and I also ripped
out the in-file changelog since it belongs here. At the time, it said:
/* Apr 15, 2004 Matthew S. Wood (mwood@realmsys.com)
*
* Implement '-b' (backup) flag.
* Implement '-S' (backup suffix) flag.
*
*
* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
*
* Fixed bug involving -n option. Essentially, -n was always in effect.
