(will close all fd's > 2 on daemonization now)
getty: fix "getty -" support, and also do not try to chown/chmod "-"
telnetd: fix "lost ctty" bug
Yet another attempt on saner function names:
bb_sanitize_server_stdio(0/1) -> bb_sanitize_stdio() + bb_daemonize();
|

few other applets: #ifdef CONFIG_ -> #if ENABLE_
traceroute: fix exposed bugs
defconfig: update

It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

bb_xx_msg calls, and convert networking/* to it.
The rest of bbox will be converted gradually.

Incomplete: xfunc() would not respect this. TODO.

to rewrite it anyway so I'll just bump that up in priority a bit).

- use shorter boilerplate while at it.

rename usage() to zcip_usage, make struct arp_packet static. This applet is
not ISO C89 compatible due to the use of C99-style comments ("c++ comments).

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....
