Aha!  You are running Linux!
	Congratulations on the choice of a GNU generation.
	I will use sgttyb tty structures.
	I will use your sockets definition header.
	I will use wait4() instead of waitpid().

If installed set-uid root, this program will put entries for its windows
in /var/run/utmp, and will also change ownership of the ttys it acquires to the
user running this program.

Done. Type 'make' to build
