Finally made more out of range handling in some base utilities. For example vi with a wrong COLUMNS env var led to segmentation fault. Ported small fixes in ifconfig 80211 part from FreeBSD (use of d value instead of atoi(val) when it was necessary) and so on.

Hi,
The patch looks okay besides a few wrong tabs which is really minor.
But I'd like to understand why you don't use strtonum() more consistently, for example you use strtol() and an ERANGE check in some other places:
- dtrwait = atoi(argv3);
+ dtrwait = strtol(argv3, NULL, 10);
+ if (errno == ERANGE)
+ usage();
Cheers,
Antonio Huete
