This fixes bug #24671.
* lisp/progmodes/cc-langs.el (c-multichar->-op-not->>-regexp): remove,
transforming into ...
(c-multichar->-op-not->>->>>-regexp) New lang const/var.
* lisp/progmodes/cc-engine.el (c-forward-<>-arglist-recur): use the new
c-multichar->-op-not->>->>>-regexp in place of the old
c-multichar->-op-not->>-regexp.
Also fix infinite loops by correcting two regexps.
* lisp/progmodes/cc-langs.el (c-last-c-comment-end-on-line-re)
(c-last-open-c-comment-start-on-line-re): Correct the regexp fragments
"\\*+[^/]" to "\\*+\\([^*/]\\|$\\)".
* lisp/progmodes/cc-fonts.el (gtkdoc-font-lock-keywords): Disallow /**/ for
doc comment fontification.

(c-beginning-of-statement-1): Set c-commas-bound-stmts rather than
c-stmt-delim-chars.

later to a substring of it.
(c-at-statement-start-p): Set c-syntactic-skip-backward from the new
variables.
(c-at-expression-start-p): Bind c-commas-bound-stmts. Use
c-stmt-delim-chars-with-comma rather than c-stmt-delim-chars in a backward
scan.
(c-guess-basic-syntax): Bind c-commas-bound-stmts rather than
c-stmt-delim-chars to itself. Bind c-commas-bound-stmts to t at another place
rather than setting c-stmt-delim-chars to c-stmt-delim-chars-with-comma.
Also fix two faulty regexps, save-match-data, and check c-major-mode-is
'c++-mode where needed.

if the sought position is in a literal, and lies between the literal start and
the entry's position.
(c-cache-to-parse-ps-state, c-parse-ps-state-below): Amend such that instead
of cacheing a state for a position after a backslash or first character of a
2-character comment delimiter, this is done for the previous character
position.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): Enhance the
analysis of case labels to handle parenthesised expressions (e.g. macros).
* lisp/progmodes/cc-langs.el (c-nonlabel-nonparen-token-key): New lang const
and lang var.

settle on the # of #define, to facilitate the regexp matching in
c-find-decl-prefix-search.

const.
(c-literal-start-regexp): Correct what was always supposed to be a "generic
string" regexp element.

(c-dposr-cpp-macro-depth): New lang variable and lang constant.
In particulr, handle multiline block comments whose newlines are not escaped.
There is an example of this in #define EXTRA_CONTEXT_FIELDS in editfns.c.
* lisp/progmodes/cc-engine.el (c-beginning-of-macro, c-end-of-macro): Enclose
the loops scanning escaped newlines with outer loops which check
heuristically for, respectively, a block comment ender and a block comment
starter on the lines we end up on. (A rigorous syntactic check would be too
slow, here.)
* lisp/progmodes/cc-langs.el (c-last-c-comment-end-on-line-re)
(c-last-open-c-comment-start-on-line-re): New language constants/variables.

being '. Fix argument in call of c-before-change-check-unbalanced-strings.
(c-parse-quotes-before-change, c-parse-quotes-after-change): Bind
case-fold-search to nil. Analyze escape constructs inside character constants
more accurately, in particular accepting as valid more than one character
after /[0-7], /x, /u, and /U. Amend calculations to account for this extra
length.
Integrate the handling of raw string and ordinary string fontification.
* lisp/progmodes/cc-defs.el (c-font-lock-flush)
(c-search-forward-char-property-without-value-on-char): new macros.

limit argument being nil.
(c-clear-char-property-with-value-on-char-function)
(c-clear-char-property-with-value-on-char): Return the position of the first

c-lineup-2nd-brace-entry-in-arglist, c-lineup-class-decl-init-+, and
c-lineup-class-decl-init-after-brace.

constants/variables.
String delimiters, including escaped new lines, of correctly terminated
strings are left in font-lock-string-face. All others get
font-lock-warning-face. The latter get syntax-table text properties on the
opening string delim and the "terminating EOL".
Correct two miscellaneous bugs: the handling of text properties on Java Mode's
generic delimiters; the handling of c-just-done-before-change.
* lisp/progmodes/cc-defs.el (c-point): New position 'eoll "end of logical line".
(c-characterp): New macro.
* lisp/progmodes/cc-fonts.el (c-font-lock-invalid-string): Removed.
(c-basic-matchers-before): Use a simple matcher in place of the form around
c-font-lock-invalid-string.
* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): Add
c-before-change-check-unbalanced-strings to the value for all modes except AWK
Mode. Also add c-before-change-check-<>-operators to Java Mode, correcting an
error in that mode's handling of generic delimiters.
(c-before-font-lock-functions): Add c-after-change-re-mark-unbalanced-strings
to the value for all modes except AWK Mode.
(c-single-quotes-quote-strings, c-string-delims): New lang variables for
future enhancements.

* lisp/progmodes/cc-mode.el (c-just-done-before-change): Do not set this
variable when a change is the alteration of text properties.
(c-basic-common-init): Set parse-sexp-lookup-properties (and the XEmacs
equivalent) also for Pike Mode.

(c-block-stmt-hangon-key): New lang const/var matching any element of the
above.
The regexp "\\<\\>", which is supposed never to match, actually matches, for
instance, where a Chinese character is directly followed by an ASCII letter.
So, replace it with "a\\`".
* lisp/progmodes/cc-defs.el (cc-fix, c-make-keywords-re)
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1)
(c-forward-<>-arglist-recur, c-forward-decl-or-cast-1)

being merely the type of a function.
(c-where-wrt-brace-construct): Deal with a struct {..} being merely the type
of a function. Rearrange the order of some Lisp forms. Insert a check for
c-protection-key ("private", etc.) alongside the checking for a label.
(c-defun-name-1): New function extracted form c-defun-name, which works within
the existing restriction. Don't regard 'at-function-end as being within the
defun any more. Recognize "struct", etc., with the new
c-defun-type-name-decl-key rather than c-type-prefix-key. Make the
recognition of a normal function more accurate.
(c-defun-name): Part left after extracting the above function. It now just
widens and calls c-defun-name-1.
(c-declaration-limits-1): New function extracted from c-declaration-limits,
which works within the existing restriction. Move LIM back one block to
account for the possibility of struct {..} as a function type. Check we're
not inside a declaration without braces.
(c-declaration-limits): Part left after extracting the above function. It now
just narrows to an enclosing decl block and calls c-declaration-limits-1.
(c-defun-name-and-limits): New function which identifies the name and limits
of the most nested enclosing declaration or macro.
(c-display-defun-name): Use c-defun-name-and-limits rather than two separate
functions (which didn't always agree on which function).

{..} as the type of a function, go back over this, too.
* lisp/progmodes/cc-langs.el (c-defun-type-name-decl-kwds)
(c-defun-type-name-decl-key): New lang const/var.
* lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Recognize
a brace list when preceded by "return" or inside parentheses, either
immediately after the "(" or following a comma.
(c-looking-at-inexpr-block): Test c-has-compound-literals rather than hard
coded C++ Mode.
(c-guess-basic-syntax, CASE 7B): Test additionally for not being just inside a
parenthesis or being at a Java "new" keyword. CASE 9: Remove the simple
minded test on the contents of a block to determine a brace list.
* lisp/progmodes/cc-langs.el (c-has-compound-literals): New lang const and lang var.
Do this by removing a broken optimization in the state cache which put
category text properties on a character between the end of the CPP construct
and the beginning of the comment. This can't work when there's no such
character.
* lisp/progmodes/cc-defs.el (c-cpp-delimiter, c-set-cpp-delimiters)
(c-clear-cpp-delimiters, c-comment-out-cpps, c-with-cpps-commented-out)

c-neutralize-syntax-in-CPP and remove the bits which applied category
properties.

new name of the function c-neutralize-syntax-in-CPP.
* lisp/progmodes/cc-engine.el (c-forward-type): Stop recognizing a "type"
starting with "throw", by using c-opt-type-modifier-prefix-key.
* lisp/progmodes/cc-langs.el (c-type-modifier-prefix-kwds): New lang const
which, in C++, doesn't contain "throw", otherwise like c-type-modifier-kwds.
(c-opt-type-modifier-prefix-key): New lang const and var, a regexp matching
any keyword in the previous lang const.
Also recognize and handle function names introduced by "extern" inside a
function.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Add a new element to
the result list which is t when our declaration is, or is to be treated as,
being at top level.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context): Detect being
inside a C++ uniform initialization and return (not-decl nil) for this case.
(c-font-lock-declarations): Use the new element 4 of the result of
c-forward-decl-or-cast-1.

optional parameter, template-class. In "class <X = Y>", fontify "Y" as a
type.
(c-font-lock-single-decl): New variable template-class, set to non-nil when we
have a construct like the above. Pass this as argument to
c-font-lock-declarators.
(c-font-lock-cut-off-declarators): Check more rigorously that a declaration
being processed starts before the function's starting position.
(c-complex-decl-matchers): Remove the redundant clause which fontified "types
preceded by, e.g., "struct"".
* lisp/progmodes/cc-langs.el (c-template-typename-kwds)
(c-template-typename-key): New lang defconsts and defvar.
Also correct two bugs where deleting WS at a BOL could leave an untyped
function declaration unfontified.
* lisp/progmodes/cc-engine.el (c-find-decl-spots): Don't set the flag
"top-level" when we're in a macro.
(c-forward-decl-or-cast-1): Recognize top-level "foo(bar)" or "foo()" in C
Mode as a implicitly typed function declaration.
(c-just-after-func-arglist-p): Don't get confused by "defined (foo)" inside a
macro. It's not a function plus arglist.
* lisp/progmodes/cc-langs.el (c-cpp-expr-functions-key): New defconst and
defvar.
* lisp/progmodes/cc-mode.el (c-fl-decl-end): After c-forward-declarator, move
over any following parenthesis expression (i.e. parameter list).
(c-change-expand-fl-region): When c-new-END is at a BOL, include that line in
the returned region, to cope with deletions at column 0.
This fix fixes the fontification of a method inside a class at the time it is
typed, when there is a protection keyword clause preceding it.
* lisp/progmodes/cc-engine.el (c-forward-keyword-clause): Handle protection
keywords.
(c-looking-at-decl-block): Avoid scanning forward over protection keyword
clauses too eagerly.

lang defconsts and defvars.
* lisp/progmodes/cc-mode.el (c-fl-decl-start): When we encounter a protection
keyword following a semicolon or brace, move forward over it before attempting
to parse a type.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

(c-ambiguous-overloadable-or-identifier-prefix-re): New c-lang-defconsts/vars.
* lisp/progmodes/cc-engine.el (c-forward-name): Do not try to parse "~" (and
two other symbols) as a cast without good evidence. Prefer an overloaded
operator in ambiguous cases.
Single quotes, even in strings and comments, are now marked with the
"punctuation" syntax-table property, except where they are validly bounding a
character literal. They are font locked with font-lock-warning-face except
where they are valid. This is done in C, C++, ObjC, and Java Modes.

needed.
(c-before-font-lock-functions): Remove c-before-after-change-digit-quote from
wherever it occurs. Insert c-parse-quotes-after-change into the entries for
the languages which need it.

silence a compiler warning.
Also (unrelated change) initialize the modes' keymaps at each loading.

on the modeline.
(c-block-comment-flag): New variable.
