gen_util mailcheck applet broken

[Jason Tackaberry <tack dok org>]

My MAIL envvar points to a Mailbox over an NFS mount and the mailcheck
part of the gen_util applet definitely does not seem to like this.  (It
simply does not work.)  Is this problem just me, or is it a bug?  (Note, I
tried changing my MAIL var to point to a local mailbox and the applet does
work fine if the file is local.)

Thanks,
Jason.
