------ 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.

26 ;;; Commentary: | |
27 | |
28 ;; This code will enable the use of the infamous 'wheel' on the new | |
29 ;; crop of mice. Under XFree86 and the XSuSE X Servers, the wheel | |
30 ;; events are sent as button4/button5 events. | |
31 | |
32 ;; I for one would prefer some way of converting the button4/button5 | |
33 ;; events into different event types, like 'mwheel-up' or | |
34 ;; 'mwheel-down', but I cannot find a way to do this very easily (or | |
35 ;; portably), so for now I just live with it. | |
36 | |

38 ;; file: | |
