Make gcc happy, replace strncat with "manual" copying
On addresses like UDP-RECVFROM with fork option every packet causes a
new child process which then reads the packet. The parent process must
wait until the packet has been read before checking again. The former
synchronization mechanism using SIGUSR1 is now replaced by a
socketpair. SIGUSR1 is no longer used for internal synchronization.
