Subject: (x_connection_signal): Call x_connection_closed properly.
X-Git-Tag: emacs-19.34~1371
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6186a4a01534ffd748f1c4a85e5a8cb6eeb16f1e;p=emacs.git

(x_connection_signal): Call x_connection_closed properly.
(x_connection_closed): Set FRAME_X_DISPLAY to 0.
(x_destroy_window): Don't do any X operations if FRAME_X_DISPLAY is 0.

(x_term_init): Use "" as 2nd arg to setlocale.

(x_connection_signal): Don't stop polling.
Don't mess with SIGALRM.
Those were relics of the superseded Dec 19 change.
