* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
#defined. That lets the system provide it, if it has it.
* syssignal.h (sigmask): Only define this if <signal.h> hasn't
given us a definition already.
* syssignal.h (sys_sigpause): Fix argument in prototype.
* sysdep.c (init_signals): The masks are called empty_mask and
full_mask, not signal_empty_mask and signal_full_mask.
(signal_handler_t): Moved ....
* syssignal.h: ... to here.
* systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct
arguments.
* emacs.c (main): Don't try to establish signal handlers for
SIGBUS and SIGSYS unless they're actually #defined.

* systty.h [HAVE_TERMIO, __DGUX]: #include <sys/ioctl.h>.
Set up Qcurrent_load_list.
(readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.
(build_load_history): Do nothing when loading pure files.
* unexelfsgi.c: New file; like unexelf.c, but tolerates program
segments above BSS.
* m/iris5d.h: New file.
* s/irix5-0.h: New file.
* process.c [__sgi] (allocate_pty): Give up immediately if pty is
inaccessible.
same dimensions as the default face, so as not to confuse the rest
of the redisplay code.
* xfaces.c (same_size_fonts): New function.
(merge_faces): Only merge in a new font from the FROM face if it
is the same size as the font in the TO face.
(redisplay_window): Update region_showing field.
(display_text_line): Set region_showing to t if will show one.
(mark_window_display_accurate): Set region_showing fields.
(redisplay_window): Update region_showing field.
(display_text_line): Set region_showing to t if will show one.
(redisplay, redisplay_window): Don't use the cursor-motion
special-case code if the region is or was highlighted.
(display_text_line): Pass those args,
describing the region if the mark is transient and active.
(display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.
* Makefile.in (srcdir, VPATH): Get this value from the top-level
Makefile.
(xmakefile): Use ${srcdir} to find the files from which we produce
xmakefile. Edit the values for srcdir and VPATH into xmakefile.
* ymakefile (srcdir, VPATH): New definitions for the Makefile
to edit.
(ALL_CFLAGS): Remove `-Is' and `-Im'; add `-I${srcdir}', and
`-I.'.
(emacs): Adjust dumping commands to deal with a separate source
directory.
(${etc}DOC): Pass `-d ${srcdir}' to make-docfile, to tell it where
to find the source files.
(prefix-args): Find the source code in ${srcdir}.
BUFFER argument has been omitted, put it in the current buffer,
for symmetry with move-marker.
* buffer.c (Fdelete_overlay): Make the overlay's markers point
nowhere, not at 1. Do this after calling redisplay_region, so
that code knows what section has changed.
