> There is still following issue with simulator building:

Fixed.

2009-08-14  DJ Delorie  <dj@redhat.com>

	* configure.in: Check for sys/select.h, termios.h, sys/socket.h,
	netinet/in.h, and netinet/tcp.h.
	* configure: Regenerate.
	* config.in: Add those headers.
	* main.c: Check for them.
	(setup_tcp_console): Disable if no networking.
	(main): Note missing networking or termios.
	* mem.c: Check for those headers.
	(stdin_ready): Disable if no termios.
	(m32c_sim_restore_console): Disable if no termios.
	(mem_get_byte): Disable console input if no termios.
