------ 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,

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. Avoid preprocessing games with names such
as play_sound_file.

Rename 'GNU Emacs' to XEmacs in the copyright and comments.

Stylistic cleanup. Avoid preprocessing games with names such
as play_sound_file.
