Works (send01 runs, but I start a complete test now). Thanks! I'm going
ahead and suggest to have at least rev 1.281 of uipc_socket.c in the
linuxolator-wiki.
Now... anyone up to porting the ltp to FreeBSD (or at least having a
look at the testcases and adopting them to our regression test)?
BTW: your key is expired.
Bye,
