[PATCH 1/3] daemon: handle freopen() failure

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

Die if stderr couldn't be sent to /dev/null when operating in inetd
mode and report the error message from the OS.

This fixes a compiler warning about the return value of freopen()
being ignored on Ubuntu 8.10.
