* 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.

Set up Qcurrent_load_list.
(readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.
(build_load_history): Do nothing when loading pure files.
(outline-minor-mode-map): New variable.
(minor-mode-map-alist): Add new entry.
(outline-minor-mode): Work with above change.
Do not set outline-regexp or outline-header-end-regexp.
* 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.
Don't call the frame and face initialization functions unless
they're bound.
* frame.el (frame-notice-user-settings): Don't make
frame-initial-frame unbound; just set it to nil.
* startup.el (command-line-1): Call frame-notice-user-settings
before displaying the startup message.
