This patch was provided by Chris Kuethe (ckuethe at math dot ualberta
dot ca).  It allows sftpd-1.45 to compile and run on OpenBSD and
Irix.

To apply this patch and rebuild:

  % cd sftpd
  % patch < openbsd-irix.patch.txt
  % make distclean         <-- if already tried to compile
  % ./configure && make
