Differences From Artifact [e17ee8f7dc]:

• File unix/uxpty.c — part of check-in [5b7da77997] at 2011-03-01 17:00:32 on branch trunk — Use pid_t more consistently. Should shut up a warning from GCC 4.6, and may conceivably help on platforms where int and pid_t aren't sufficiently similar. (user: jacob size: 26522)

To Artifact [ce2a2f8e82]:

• File unix/uxpty.c — part of check-in [c736ac142e] at 2011-03-02 13:12:42 on branch trunk — Colin Watson reports that gnome-session has been known to leave SIGPIPE ignored in its child processes, leading to unexpected behaviour inside pterms. (The gnome-session I'm sitting in front of doesn't seem to do this as far as I can tell, but I don't doubt there are some that do.) Add SIGPIPE to the list of signals we reset to default behaviour before launching pterm's child process. (user: simon size: 26575)
