* 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.
