This syncs recent refactorings from glibc, and incorporates:
2018-10-15 libc-config: merge from glibc
2018-10-15 regex: depend on libc-config
* .gitignore: Do not ignore m4/_*.m4.
* lib/cdefs.h: New file, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/libc-config.h, m4/__inline.m4: New files, copied from Gnulib.
* lib/regcomp.c, lib/regex.c, lib/regex_internal.c:
* lib/regex_internal.h, lib/regexec.c:
Copy from glibc via Gnulib.
This is minor refactoring that should not affect Emacs builds.
It incorporates:
2018-10-12 Make better use of Autoconf
* m4/environ.m4, m4/fsusage.m4, m4/manywarnings.m4, m4/socklen.m4:
Copy from Gnulib.
* lisp/progmodes/cc-cmds.el, lisp/progmodes/cc-defs.el
lisp/progmodes/cc-engine.el, lisp/progmodes/cc-fonts.el
lisp/progmodes/cc-langs.el: Add lots of edebug specs.
* lisp/progmodes/cc-engine.el (c-state-maybe-marker): Tidy up so as to
evaluate an argument only once at runtime.
Problem reported by Paul Pogonyshev (Bug#33034).
* src/lisp.h (union specbinding): New member unwind.eval_depth.
* src/eval.c (record_unwind_protect, set_unwind_protect): Set it.
(do_one_unbind): Use it.
* src/json.c (struct json_buffer_and_size): New member
inserted_bytes.
(json_insert): Instead of creating a string and inserting it
into the current buffer, copy the unibyte text into the gap.
(struct json_insert_data): New member inserted_bytes.
(json_insert_callback): Update commentary. Pass the
inserted_bytes value to json_insert and on its return copy the
updated value back into DATA.
(Fjson_insert): Decode the unibyte text inserted into the gap.
Call before-change-functions and after-change-functions only
once, before and after processing the insertion of the entire
JSON representation.
* test/src/json-tests.el (json-insert/throw): Adapt to the
modified implementation of json-insert: it no longer calls the
modification hooks once for each inserted chunk of JSON
representation.
* lisp/net/tramp-archive.el (tramp-archive-autoload-file-name-handler):
New defalias.
(tramp-register-archive-file-name-handler): Use it.
* lisp/net/tramp.el (tramp-file-name-for-operation): Change it for
`expand-file-name'.
(tramp-file-name-handler): Unset `file-name-handler-alist' when
autoloading a Tramp file name handler.
(tramp-autoload-file-name-handler): Always unload Tramp file name
handlers.
(tramp-register-file-name-handlers)
(tramp-unload-file-name-handlers): Simplify.
There were two problems with the original implementation:
1. It changed the behavior of insert-abbrev-table-description when
READABLE is nil to sometimes insert one Emacs Lisp expression and
sometimes insert nothing.
2. It broke the tests.
This commit reworks this so that insert-abbrev-table-description
always inserts an expressions even if no abbrevs need to be saved and
making only write-abbrev-file check that a table has any abbrevs to
save before calling insert-abbrev-table-description. This duplicates
the work of filtering the table for savable abbrevs, but the benefit
of keeping the API is worth it.
* doc/lispref/abbrevs.texi (Abbrev Tables): Update documentation.
* lisp/abbrev.el (write-abbrev-file): Skip tables without user abbrevs
(insert-abbrev-table-description): Always insert the define
expression.
(abbrev--table-symbols): New function.
* test/lisp/abbrev-tests.el (abbrev--table-symbols-test):
Add test for abbrev--table-symbols.
* lisp/registry.el (registry-collect-prune-candidates): This `cdr' was
an error: it meant that the last key in the precious list, would be
considered a nil. Since the precious list only contains the symbol
'mark by default, marks were never considered precious.
* doc/misc/gnus.texi (Store arbitrary data): Fix typo: "marks" should
be "mark".
* src/bignum.c (make_neg_biguint): New function.
* src/lread.c (read1): Do not mishandle an unquoted symbol
with name equal to something like "1\0x", i.e., a string
of numeric form followed by a NUL byte.
Formerly these symbols were misread as numbers.
(string_to_number): Change last argument from an integer flag
to a pointer to the length. This lets the caller figure out
how much of the prefix was used. All callers changed.
Add a fast path if the integer (sans sign) fits in uintmax_t.
Update comments and simplify now that bignums are present.
* src/print.c (print_object): Fix quoting of symbols that look
like numbers, by relying on string_to_number for the tricky
cases rather than trying to redo its logic, incorrectly. For
example, (read (prin1-to-string '\1e+NaN)) formerly returned
"1e+NaN", which was wrong: a backslash is needed in the output
to prevent it from being read as a NaN. Escape NO_BREAK_SPACE
too, since lread.c treats it like SPACE.
* test/src/print-tests.el (print-read-roundtrip):
Add tests illustrating the abovementioned bugs.
14c032d Avoid assertion violations in nonsensical calls to 'signal'
b99192f * lisp/simple.el (transient-mark-mode): Correct documentation...
7e42294 Update the locale and language database
8c53d9f Fix a typo in a doc string.
79bda3b Make nneething allow CRLF-encoded files (bug#32940)
This bug on 32-bit platforms was caused by the timespec_hz
definition going haywire because the C expression
FIXNUM_OVERFLOW_P (MOST_POSITIVE_FIXNUM) did not work in #if.
Eventually the numeric problem showed up as a malfunctioning
cursor (Bug#32992). Fix the problem with MOST_POSITIVE_FIXNUM.
By the way, make_fixnum should check for integer overflow when
debugging; this would have made it easier to track this bug down.
But one fix at a time.
* src/lisp.h (INTTYPEBITS): Now a macro, so usable in #if.
(MOST_POSITIVE_FIXNUM): Mention it’s used in #if.
(occur-mode, occur-1): Use it.
(occur--region-start, occur--region-end, occur--region-start-line)
(occur--orig-line): Remove vars.
(occur-engine): Fix left over use of occur--region-start-line.
Put the region info in the "list of buffers" used for multi-occur.
(occur--parse-occur-buffer): Remove.
(occur): Pass the region to occur-1 as an overlay.
(occur-1): 'bufs' is now a list of buffers or overlays.
(occur-engine): 'buffers' is now a list of buffers or overlays.
* lisp/replace.el (occur-revert-function): Use the value of
occur-revert-function from the correct buffer. (Bug#32987)
* test/lisp/replace-tests.el (replace-occur-revert-bug32543)
(replace-occur-revert-bug32987): New tests.
Require cl-lib. Remove redundant :group args.
(timeclock-status-string): Avoid 'setq'.
(timeclock-ask-for-project, timeclock-ask-for-reason):
Completionu tables can be simple lists of strings.
(timeclock-read-moment): Doesn't deserve to be defsubst (most of the
others don't either, admittedly).
(timeclock-entry): New type.
(timeclock-entry-begin, timeclock-entry-end, timeclock-entry-project)
(timeclock-entry-comment): Define via 'cl-defstruct'.
(timeclock-entry-list-projects, timeclock-day-list-projects):
Avoid add-to-list on lexical vars.
(timeclock-day-list): Use 'push'.
(timeclock-log-data): Use 'pcase'.
(timeclock-mean): Simplify.
(timeclock-generate-report): Use dotimes.

first one with 'error', to avoid assertion violations further
down the line. (Bug#32961)
