[xemacs-hg @ 2001-06-10 10:42:16 by ben] ------ signal-code changes ------ data.c, device-tty.c, emacs.c, floatfns.c, linuxplay.c, nas.c, process-unix.c, signal.c, sunplay.c, sysdep.c, syssignal.h: use EMACS_SIGNAL everywhere instead of playing preprocessing games with signal(). s\windowsnt.h, s\mingw32.h, syssignal.h: Remove mswindows signal code from s+m headers and move to syssignal.h as one of the five ways of signal handling, instead of playing preprocessing games. fileio.c, sysdep.c: Rename sys_do_signal to qxe_reliable_signal. signal.c, process-unix.c, profile.c: Create set_timeout_signal(); use instead of just EMACS_SIGNAL to establish a signal handler on a timeout signal; this does special things under Cygwin. nt.c: Eliminate term_ntproc(), which is blank; used as a SIGABRT handler, which was wrong anyway. nt.c, win32.c: Move signal code from nt.c to win32.c, since Cygwin needs it too when dealing with timeout signals. s\cygwin32.h: Define CYGWIN_BROKEN_SIGNALS. ------ other changes ------ s\mingw32.h: Fix problems with NOT_C_CODE being in the wrong place and excluding defines needed when building Makefile.in.in. filelock.c, mule-canna.c, mule-ccl.c, mule-ccl.h, ralloc.c, unexalpha.c, unexapollo.c, unexcw.c, unexelfsgi.c, unexnt.c, unexsni.c, s\aix3-1.h, s\bsd4-1.h, s\bsd4-2.h, s\bsd4-3.h, s\cxux.h, s\cygwin32.h, s\dgux.h, s\dgux5-4r2.h, s\dgux5-4r3.h, s\dgux5-4r4.h, s\ewsux5r4.h, s\gnu.h, s\hpux.h, s\iris3-5.h, s\iris3-6.h, s\irix3-3.h, s\linux.h, s\mingw32.h, s\newsos5.h, s\nextstep.h, s\ptx.h, s\riscix1-1.h, s\riscix1-2.h, s\rtu.h, s\sco4.h, s\sco5.h, s\template.h, s\ultrix.h, s\umax.h, s\umips.h, s\unipl5-0.h, s\unipl5-2.h, s\usg5-0.h, s\usg5-2-2.h, s\usg5-2.h, s\usg5-3.h, s\usg5-4.h, s\windowsnt.h, s\xenix.h: Rename 'GNU Emacs' to XEmacs in the copyright and comments. nas.c: Stylistic cleanup.

Fix other references to GNU Emacs that should be XEmacs or just Emacs. files.el: Fix warning. simple.el: transpose-line-up/down will now move the region up or down by a line if active. cvtmail.c, fakemail.c, gnuserv.c, gnuserv.h, gnuslib.c, make-msgfile.c, make-path.c, pop.c, pop.h, profile.c, tcp.c: Rename 'GNU Emacs' to XEmacs in the copyright.
