* lisp/progmodes/cc-mode.el (c-mode-help-address):
Switch to bug-gnu-emacs. This is an alias for the previous
submit@debbugs address, except that if no Package header can be found,
as often seems to happen for cc-mode reports, debbugs will assign
the report to the "emacs" package rather than to "debbugs.gnu.org".

lisp/progmodes/cc-defs.el, lisp/progmodes/cc-engine.el,
lisp/progmodes/cc-fonts.el, lisp/progmodes/cc-langs.el,
lisp/progmodes/cc-mode.el: Change the explicit def-edebug-spec for many macros
into a (declare (debug ...) ..) form. Add such forms to macros which were
previously lacking def-edebug-spec forms.

lisp/progmodes/cc-align.el, lisp/progmodes/cc-engine.el,
lisp/progmodes/cc-vars.el (c-syntactic-context, c-syntactic-element): Declare
these as special variables.
lisp/progmodes/cc-bytecomp.el (cc-bytecomp-debug-msg): prefix the parameter
ARGS with a _, and remove an `ignore' call.
lisp/progmodes/cc-cmds.el (c-where-wrt-brace-construct): Remove `kluge-start',
an unused variable.
(c-while-widening-to-decl-block): Add an extra parameter, which suppresses
the generation of a setting of variable `where'.
(c-defun-name-and-limits): Remove variable `where' from the function and use
the new argument to the previous macro.
lisp/progmodes/cc-engine.el (c-cache-to-parse-ps-state): Remove two unneeded

c-invalidate-macro-cache from the entries it's in, moving it to....
* lisp/progmodes/cc-mode.el (c-before-change): Call c-invalidate-macro-cache
directly from the functions, after the call to c-invalidate-state-cache.

:: tokens. Fontify new system variable names FPAT, FUNCTAB, PREC, ROUNDMODE,
SYNTAB. Fontify new keywords BEGINFILE and ENDFILE. Fontify new system
functions asorti, dcngettext, isarray, patsplit, typeof. Fontify the new
directives @include, @load, @namespace. Call
c-awk-font-lock-invalid-namespace-separators as a matcher.
* lisp/progmodes/cc-fonts.el (top level): No longer require 'cc-awk.
* lisp/progmodes/cc-langs.el (c-before-context-fontification-functions): Give
AWK the value c-awk-context-expand-fl-region rather than nil.

over unary operators, add a check (> (point) lim) to avoid certain infinite

Determine the enclosing brace to pass as arguments to
c-looking-at-or-maybe-in-bracelist.
This fixes bug #25706. It particularly pertains to .h files which contain
only macro definitions. Many of these files are to be found, for example, in
the driver sections of the Linux kernel.

(c-fl-decl-end): Give search limits to, or amend existing ones to
c-backward-syntactic-ws, c-forward-syntactic-ws, skip-chars-backward,
skip-chars-forward.
This corrects both the fontification and indentation of these things, fixing
bug #42270.
* lisp/progmodes/cc-engine.el (c-do-declarators): Skip over "hangon keys" and
noise macros whilst scanning a putative C++ function.
(c-forward-decl-or-cast-1): When checking for typeless functions, skip over
"hangon keys" and noise macros.
* lisp/progmodes/cc-mode.el (c-fl-decl-end): Deal with certain invalid
"nested declarators" by scanning over them with a recursive call of
c-fl-decl-end.
* lisp/progmodes/cc-vars.el (c-noise-macro-names)
(c-noise-macro-with-parens-names): State in the doc strings that if either of
these is a regexp, it must have a submatch 1 which matches the noise macro
exactly.
These sometimes gave rise to the tail of a buffer being "stringed out".
* lixp/progmodes/cc-defs.el (c-will-be-unescaped): New macro.

The bug involved failing to set c-new-END correctly, which lead to an
args-out-of-range error when after-change-functions was invoked twice without
an intervening invocation of before-change-functions.
* lisp/progmodes/cc-mode.el (c-after-change): Correct a coding error in the
handling of c-just-done-before-change.
without an intervening call to after-change-functions. This would have been a
workaround to bug #38691 had the causes of that bug not been removed.
* lisp/progmodes/cc-mode.el (c-just-done-before-change): Add an extra value to
this variable, 'whole-buffer, this being set by c-before-change as a signal to
c-after-change that although c-before-change has run, it has assumed the
entire buffer as the change region.
(c-before-change, c-after-change): Adapt to the new meaning of the above.
In particular, with these unterminated quotes on each of two adjacent lines,
the following text was spuriously fontified with string face.

(c-search-backward-char-property-with-value-on-char): New macro.
* lisp/progmodes/cc-mode.el (c-clear-string-fences): Check whether there is an
unmatched quote at a lower buffer position which should match the current
quote, rather than wrongly assuming the latter is unmatched and marking it
with a punctuation syntax.
(c-font-lock-fontify-region): Ensure all pertinent parts of the buffer have
string fence properties applied before performing any syntactic operations on
it; in particular, this applies to a quote at an earlier buffer position which
"matches" one inside the region about to be fontified.
* lisp/progmodes/cc-mode (c-font-lock-fontify-region): Widen in this function,
to ensure that the CC Mode font locking mechanism can examine characters
outside the given region.
Also make miscellaneous amendments.
* lisp/progmodes/cc-align.el, lisp/progmodes/cc-cmds.el
* lisp/progmodes/cc-defs.el, lisp/progmodes/cc-engine.el

such that an element's END element will be nil if the pertinent literal is
open at EOB.
(c-full-pp-to-literal): Before setting the aforementioned END element, check
that we're no longer in a literal. (c-literal-limits): When
c-full-pp-to-literal returns a list with a nil END element, replace this by
(point-max) to keep the interface of c-literal-limits unchanged.
* lisp/progmodes/cc-mode.el (c-after-change-mark-abnormal-strings): Having
found a string quote, check it is not inside an unterminated comment (i.e. one
at EOB).
