* process.c (process_send_signal): Don't send SIGTSTP if the

	system doesn't have that facility.

	* process.c: [USG5] Don't include <fcntl.h>.
	[USG] Don't bother including termios, termio, or fcntl; systerm.h
	takes care of all that.
	Remove the "mis;tak-+;;" line from the code; apparently this
	section of code does get used.

	* process.c (wait_reading_process_input): Put comments around
	text following #endif.
