Rename: bsd4-3.h -> bsd-common.h; irix6-0.h -> irix6-5.h.
Delete: template.h (useless).
Delete a whole bunch of obsolete stuff in sol2.h, linux.h,
freebsd.h -- assume anything over 10 years old is sufficiently
obsolete to be deleted.
Remove LIBS_DEBUG, C_DEBUG_SWITCH, C_OPTIMIZE_SWITCH, KERNEL_FILE,
LDAV_SYMBOL, most remaining PTY stuff, remaining TERMINFO/TERMCAP
stuff. Update README appropriately.
Remove stuff in hpux11-shr.h duplicated in hpux11.h.
Remove sco7.h, identical with usg5-4-2.h.
Remove unused POSIX flag, BROKEN_TIOC*, NO_SIOCTL_H.

* m/arm.h:
* m/hp800.h:
* m/intel386.h:
* m/mips.h:
* m/powerpc.h:
* m/sparc.h:
* m/template.h:
Temporarily ifdef out all defines involving load-average stuff --
using define ENABLE_SM_FILE_DECLS_OF_LOADAVG_STUFF, which is not
defined.
I'm pretty sure getloadavg.c will take care of defining stuff
properly on all systems without the need to duplicate the info
in m/*. --ben
Delete LIBS_TERMCAP; configure auto-handles this.
Delete extra stuff in hp800.h.
Delete C_DEBUG_SWITCH, C_OPTIMIZE_SWITCH, LDAV_SYMBOL; incorporate
some stuff into configure.ac.

| 30 ;; These are extensions to Emacs Lisp that provide a degree of | |
| 31 ;; Common Lisp compatibility, beyond what is already built-in | |
| 32 ;; in Emacs Lisp. | |
| 33 ;; | |
| 34 ;; This package was written by Dave Gillespie; it is a complete | |
| 35 ;; rewrite of Cesar Quiroz's original cl.el package of December 1986. | |
| 36 ;; | |
| 37 ;; This package works with Emacs 18, Emacs 19, and XEmacs/Lucid Emacs 19. | |
| 38 ;; | |
| 39 ;; Bug reports, comments, and suggestions are welcome! | |
| 40 | |
| 41 ;; This file contains emulations of internal routines of the older | |
| 42 ;; CL package which users may have called directly from their code. | |
| 43 ;; Use (require 'cl-compat) to get these routines. | |
| 44 | |
| 45 ;; See cl.el for Change Log. | |
