Hi just looked at the diffs for /usr/src/secure/lib/libssh/config.h between
version 1.6 and 1.7 from the CVSWeb tool.  It seems that:

In version 1.6:

/* Define if you want TCP Wrappers support */ 	 
 #define LIBWRAP 1

and in version 1.7:

/* Define if you want TCP Wrappers support */
/* #undef LIBWRAP */

Assuming that if tcp_wrappers were to be called, then a 

strings /usr/sbin/sshd | grep request_init

would produce output, while now it does not.  So although sshd is *linked*
with libwrap, it does not call request_init(), fromhost() and refuse()
because LIBWRAP is undefined in config.h for libssh, right?
