OpenSSH-2.1: FROM in 'w' empty?

[Pekka Savola]

Hello all,

I had more time to dig into this problem.  Configure script would print
stuff like:
checking for ut_host field in utmp.h... ossh_cv_utmp_h_has_ut_host

instead of:
checking for ut_host field in utmp.h... yes

This is caused by discontinuation of an undocumented feature of
/bin/sh.  If you have bash-2.x as your /bin/sh, the configure script goes
wrong.

I patched configure and aclocal.m4.  The method used works for both bash1
and bash2, so the changes should be backward compatible.  I tested this
syntax on a couple of Redhat boxes and on Irix.

Regards,
  Pekka
