quite building operators dynamically (from NetBSD, Adam Glass)

strip leading spaces from "integers" (bug report 4.4BSD-alpha/bin/1)
check for underflow, overflow, trailing garbage, use strtol(3)
use err/warn from the C library, some minor lint/cleanups

[ ] used *(char *)NULL (net2/bin/16). also, /bin/[ should work
just like [

atol is in stdlib.h
