Bug 1251

The configure script's check for a compatible 'grep' fails when the one on my system apprears to be acceptable.  My OS is LynxOS 4.0 and my grep version is...
$ grep -V
GNU e?grep, version 1.6

There are two issues why this fails.  First, my grep does not support long options, so 'grep --version' on line 3169 fails.  Then in the default case, the test "grep -e 'GREP$' -e '-(cannot match)-' ..." on line 3208 doesn't match.  I found that my older version of grep appears to /AND/ all of the '-e' expressions where newer versions of grep /OR/ the '-e' expressions.

I searched through the script and it doesn't appear to me that the behavior described above is utilized anywhere else.  As a hack I changed line 3169 to "grep -V" and the configure script completed successfully.  Also, I have installed openSSH 4.3p2 previously on this same platform and I didn't run into this issue.
