freebsd-ports/security/openssh/files/strlcpy.c
Brian Feldman ac3b838e7f Quite a bit of change to OpenSSH made:
Add "/usr/local/bin" to _PATH_STDPATH (makes scp work inbound, for instance.)
Fetch OpenSSH from OpenBSD's src tree.  This uses a script and ftp(1).
Add strlcpy.c to ssh/lib, so this port should build on 3.X now.
Make TCP_WRAPPERS conditional on /usr/include/tcpd.h like the PR, so it
 should build on older RELEASEs without TCP Wrappers.

The PR is still open because I am taking more from it.
