* 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}.
config.h file directly, instead of having lots of -D flags.
* Makefile.in (CFLAGS): Don't make this carry DEFS from the
configure script; the coding standards say that CFLAGS should be
left for the user to tweak.
* Makefile.in (LN_S): New variable, edited by top Makefile.
(SUBMAKEFILE): New variable, containing all flags to pass to
recursive makes.
* config.h.in: Add extra line to top, in case autoconf gets fixed
and decides not to add Makefile-style comments to the top of the
files it generates which we are forced to lop off.
Indicate that the boolean macros here get their definitions via
the DEFS Makefile variable.
Adjust the operating system and machine #includes to use
autoload's @cookies@.
(RETSIGTYPE): Give this a default value.
(SIGTYPE): Set this from RETSIGTYPE.
(LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Get values via @cookies@.
* Makefile.in (DEFS): Renamed from CONFIG_CFLAGS.
(xmakefile): Pass CFLAGS to ${CPP}.
* Makefile.in (tagsfiles): Remove external-lisp from this list of
files; we're not distributing it, so the normal build process
shouldn't depend on it.
they don't exist anymore.
* Makefile.in (distclean): Don't delete autosave or backup files.
(extraclean): New target; like distclean, but delete autosave
and backup files too.
* Makefile.in (srcdir): New variable, not fully implemented.
(xmakefile): Turn -g and -O in CFLAGS into C_DEBUG_SWITCH and
C_OPTIMIZE_SWITCH in C_SWITCH_SITE's definition. Delete junk.cpp
when done.
* ymakefile (archlib): Variable definition deleted. Run programs
from ../lib-src directly, or use ${archlibdir}.
(${etc}DOC): Run make-docfile from ${libsrc}, not ${archlib}.
(${archlib}make-docfile, ${archlib}emacstool): Use ${libsrc}, not
${archlib}.
