This patch is because Hurd does not support NOFILE. It is against current

cvs.

The Debian bug report says, "The upstream source makes use of NOFILE
unconditionalized.  As the Hurd doesn't have an arbitrary limit on the
number of open files, this is not defined.  But _SC_OPEN_MAX works fine
and returns 1024 (applications can increase this as they want), so I
suggest the below diff.  Please forward this upstream, too."
