There are a lot of tty_warn(0,...) and syswarn(0,...) which probably ought to be tty_warn/syswarn(1,...) to force an error exit. However some are used in interactive parts (eg opening a continuation archive) where there is a separate retry loop. So we just pass a failure code out to main() - how quaint! This should now cause the NetBSD build to fail when gzip tries to write to a non-existant directory. (I suspect there are still many errors that don't get reported correctly.)
