continually generating new ones.
cc-engine.el (c-state-old-cpp-beg-marker, c-state-old-cpp-end-marker):
New variables.
(c-append-lower-brace-pair-to-state-cache): Start a backward search for
"}" definitively outside CPP constructs.
(c-remove-stale-state-cache): Inform the caller of a need to search back
for a brace pair in certain circumstances.
(c-state-maybe-marker): New macro.
(c-parse-state): Reuse markers when appropriate.
cc-engine.el (c-state-nonlit-pos-interval): change value 10000 -> 3000.
(c-state-safe-place): Reformulate so it doesn't stack up an infinite
number of wrong entries in c-state-nonlit-pos-cache.
(c-determine-limit-get-base, c-determine-limit): New functions to
determine backward search limits disregarding literals.
(c-find-decl-spots): Amend commenting.

cc-fonts.el (c-make-font-lock-BO-decl-search-function): Give a limit to a
backward search.
(c-font-lock-declarations): Fix an occurrence of point being undefined.
Check additionally for point being in a bracelist or near a macro
invocation without a semicolon so as to avoid a fruitless time consuming
search for a declarator. Give a more precise search limit for
declarators using the new c-determine-limit.
Tidy up and accelerate c-in-literal, etc. by using the c-parse-state
routines. Limit backward searching in c-font-lock-enclosing.decl.
cc-engine.el (c-state-pp-to-literal): Return the pp-state and literal
type in addition to the limits.
(c-state-safe-place): New defun, extracted from c-state-literal-at.
(c-state-literal-at): Use the above new defun.
(c-slow-in-literal, c-fast-in-literal): Removed.
(c-in-literal, c-literal-limits): Amended to use c-state-pp-to-literal.
cc-fonts.el (c-font-lock-enclosing-decls): Check for being in a literal.
Add a limit for backward searching.
cc-mode.el (awk-mode): Don't alias c-in-literal to c-slow-in-literal.
correctly, using the "virtual semicolon" mechanism.
cc-defs.el: Update "virtual semicolon" comments.
cc-engine.el (c-crosses-statement-barrier-p): Recoded to scan one line at
at time rather than having \n and \r explicitly in c-stmt-delim-chars
(for some modes, e.g. AWK).
(c-forward-label): Amend for virtual semicolons.
(c-at-macro-vsemi-p, c-macro-vsemi-status-unknown-p): New functions
cc-fonts.el (c-font-lock-declarations): Take account of the new C macros.
cc-langs.el (c-at-vsemi-p-fn, c-vsemi-status-unknown-p-fn): move to
earlier in the file.
(c-opt-cpp-symbol, c-line-comment-start-regexp): New language variables.
(c-opt-cpp-macro-define): Make into a full language variable.
(c-stmt-delim-chars, c-stmt-delim-chars-with-comma): Special value for
AWK Mode (including \n, \r) removed, no longer needed.
cc-mode.el (c-mode, c++-mode, objc-mode): Invoke
c-make-macro-with-semi-re.
cc-vars.el (c-macro-with-semi-re, c-macro-names-with-semicolon): New
variables.
(c-make-macro-with-semi-re): New function
cc-mode.texi (Indentation Commands): Mention "macros with semicolons".
(Other Special Indentations): Add an xref to "Macros with ;".
(Customizing Macros): Add stuff about syntax in macros. Add an xref to
"Macros with ;".
(Macros with ;): New page.
cc-fonts.el (c-complex-decl-matchers): Add in special detection for a
java annotation.
cc-engine.el (c-forward-decl-or-cast-1): Add in special detection for a
java annotation.
cc-langs.el (c-prefix-spec-kwds-re): Remove the special handling for
java.
(c-modifier-kwds): Remove the regexp "@[A-za-z0-9]+".
cc-langs.el (c-has-bitfields): New lang variable.
(c-symbol-chars): Now exported as a lang variable.
(c-not-primitive-type-keywords): New lang variable.
cc-fonts.el (c-font-lock-declarations): Jump over the QT keyword "more"
to prevent "more slots: ...." being spuriously parsed as a bitfield
declaraion.
cc-engine.el (c-beginning-of-statement-1): Refactor and enhance to handle
bitfield declarations.
(c-punctuation-in): New function.
(c-forward-decl-or-cast-1): Enhance CASE 3 to handle bitfield
declarations properly.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Remove a
narrow-to-region call that cuts context off the end (Bug#7722).
* lisp/progmodes/cc-engine.el (c-forward-<>-arglist-recur): Refactor
nested if-forms with a simple cond.
(c-forward-<>-arglist): Revert 2011-01-31 change.
