Subject: (X_CONNECTION_LOCK_FLAG): New macro.
X-Git-Tag: emacs-19.34~1166
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6cf0ae869df1538819550731584ebb189144d176;p=emacs.git

(X_CONNECTION_LOCK_FLAG): New macro.
(x_connection_close_if_hung): New subroutine, at the end of the file.
Include X11/Xlibint.h only for this function.
#undef bcopy, bzero, bcmp, min, max first.
Define malloc and free to avoid type conflicts.
(x_connection_signal): Use x_connection_close_if_hung.
