strtonum(3) in FreeBSD?

I agree with both of the latter two problems...I am wondering if it'd be
possible to talk to Theo about changing strtonum(3) in OpenBSD as well...we
(the MirOS Project) asked Theo about the intmax_t idea, and he simply replied
"No" (in classic Theo fashion, sans flames) 

Having no way to distinguish a valid zero is slightly retarded; in general, I
think it's a decent idea, but needs some polishing up. I'm not pushing real
hard for it though, since some other utilities exist (atoi(), strtol(), etc),
but it would be something handy to have around...
