build patch
Makefile.in.in: Move src deletions to src/Makefile.in.in.
dump-paths.el, dumped-lisp.el: Delete. Combine stuff into setup-paths.el.
find-paths.el: Removed.
Make this file contain generic routines only. Move stuff to
compute Emacs roots to setup-paths.el.
startup.el: Removed.
Move these variables into setup-paths.el.
setup-paths.el, startup.el: Removed.
Combine all high-level code for computing the paths into
setup-paths.el. Create new function startup-find-load-path to
encapsulate all logic for computing `load-path'. Eliminate
invocation-directory and invocation-name parameters since
there is no point (false generality) -- the code references
other globals, which cannot be specified. Eliminate some code
duplicated between setup-paths.el and startup.el. Clean up
the debug-paths code and output load-path in addition.
Add logic to paths-emacs-root-p to support separated source
and build trees.
loadup.el, make-docfile.el, update-elc-2.el, update-elc.el: Rewrite to allow for separated source and build trees, as may occur
in MS Windows.
NOTE TO BUILD HACKERS:
loadup.el, make-docfile.el, update-elc.el and update-elc-2.el made two
assumptions that are no longer correct:
(1) The source and build trees are in the same place.
(2) They can make assumptions about where `.' is.
These files now compute the locations of the source and build
roots at the top of the file. *ALL* constant file names or path
snippets must now be made absolute using expand-file-name and one
of these roots.
dumped-lisp.el, packages.el: Removed.
Remove some unused lists of Lisp files. packages-hardcoded-lisp
(empty, in any case) moved to dumped-lisp.el.
startup.el: When a compiled init file is out-of-date wrt the uncompiled
version, load the uncompiled version and issue a nasty warning.
update-elc-2.el: Force touching of auto-autoloads files when REBUILD_AUTOLOADS
was set.
update-elc.el: Fix code that checks whether dumping is necessary to check against
xemacs.dmp, not xemacs.exe, when Unix and pdump.
lwlib-Xm.c: Fix compile warning.
README, config.inc.samp, xemacs.mak: -- Major reorganization and cleanup.
-- Add support for separated build tree and source tree.
-- Delete all support for X Windows building, since it's
totally bit-rotten and will never be fixed up. Instruct
people to use Cygwin if they want such support.
make-build-dir: New script to create a skeleton build tree for use with
separated build and source tree compilation.

Just use pdump.
Makefile.in.in: Lots o' cleanup. Use names like LISP, SRC instead of
lispdir, srcdir, for consistency with xemacs.mak and the
conventions in the rest of the file. Eliminate use of ${...}
in favor of $(...), to make it easier to move code between
this file and xemacs.mak. Fix dependency handling wrt
NEEDTODUMP to eliminate problems some people (e.g. Vin) have
been seeing with non-GNU makes. Write a long section about
the subtle but oh-so-important differences in dependency
processing between nmake, make, and GNU make. Add
unicode-encapsulate target, from xemacs.mak.
chartab.c, lrecord.h: Fix crash due to attempt to free objects across dump/undump.
