Fixes debbugs#19206.
cc-bytecomp.el (cc-bytecomp-compiling-or-loading): new function which
walks the stack to discover whether we're compiling or loading.
(cc-bytecomp-is-compiling): Reformulate, and move towards beginning.
(cc-bytecomp-is-loading): New defsubst.
(cc-bytecomp-setup-environment, cc-bytecomp-restore-environment): Use
the
above defsubsts.
(cc-require-when-compile, cc-bytecomp-defvar)
(cc-bytecomp-defun): Simplify conditionals.
cc-defs.el (cc-bytecomp-compiling-or-loading): "Borrow" this function
from cc-bytecomp.el.
(c-get-current-file): Reformulate using the above.
(c-lang-defconst): Prevent duplicate entries of file names in a symbol's
'source property.

cc-langs.el (c-make-init-lang-vars-fun): Use cc-bytecomp-is-compiling.
The main change is to only use the `category' text-property only when
available. For that many calls are changed to use c-get-char-property,
c-next-single-property-change, c-sc-scan-lists,
c-sc-parse-partial-sexp, c-unmark-<->-as-paren.
* lisp/progmodes/cc-align.el (c-lineup-respect-col-0): New function.
* lisp/progmodes/cc-cmds.el (c-forward-into-nomenclature)

not available.
(c-beginning-of-defun, c-end-of-defun, c-mark-function)
(c-indent-line-or-region): Use c-region-is-active-p.
* lisp/progmodes/cc-defs.el (c-version): Bump up to 5.33.
(c-use-category): New const.
(c-next-single-property-change): New macro.
(c-region-is-active-p): Prefer region-active-p when available.
(c-search-backward-char-property): Fix old min/max typo; probably
a copy/paste error.
(c-mark-<-as-paren, c-mark->-as-paren, c-unmark-<->-as-paren):
Turn them into macros that obey c-use-category.
(c-sc-scan-lists-no-category+1+1, c-sc-scan-lists-no-category+1-1)
(c-sc-scan-lists-no-category-1+1, c-sc-scan-lists-no-category-1-1)
(c-sc-scan-lists, c-sc-parse-partial-sexp)
(c-looking-at-non-alphnumspace): New macros.
(c-sc-parse-partial-sexp-no-category): New function.
(c-emacs-features): Add `category-properties' element.

Handle the case where categories are not available.
(c-record-parse-state-state, c-replay-parse-state-state):
Handle marker values.
(c-before-change-check-<>-operators): Look for the `syntax-table'
property rather than for the corresponding `category'.
(c-looking-at-decl-block): Remove unused var
`c-disallow-comma-in-<>-arglists'.
(c-forward-<>-arglist-recur): Remove unused var
`orig-record-found-types'.
* lisp/progmodes/cc-langs.el (c-modified-constant): New lang var.
(c-known-type-key): Don't make a list just to throw it away.
* lisp/progmodes/cc-bytecomp.el (cc-bytecomp-unbound-variables)

(c-basic-common-init): Initialize it.
(c-common-init): Only use mode-require-final-newline when available.
(c-before-change): Check and set c-just-done-before-change.
(c-after-change): Re-set c-just-done-before-change.
(c-advise-fl-for-region): New macro.

Advise if needed.
cc-defs.el, cc-engine.el, cc-fonts.el, cc-langs.el, cc-menus.el,
cc-mode.el, cc-styles.el, cc-subword.el, cc-vars.el: Add 2006 to the
copyright statement.
cc-awk.el: (c-awk-after-change): Protect the match data with
save-match-data. It was being corrupted when Font Lock was not enabled.
(ii): Fix a typo.
cc-cmds.el, cc-mode.el, cc-engine.el (c-update-modeline): Concatenate the
minor mode indicators directly onto mode-name, removing
c-submode-indicators. Sometimes, c-s-i got separated from the mode name
on the mode line.
cc-cmds.el, cc-mode.el: Rename c-hungry-backspace to
c-hungry-delete-backwards, at the request of RMS. Leave the old name as
an alias.
cc-cmds.el (c-electric-brace, c-electric-semi&comma, c-electric-colon):
Correct doc-strings: "/ln" -> "/la".
cc-cmds.el (c-electric-brace): Fix clean-up brace-else-brace (error due
to mbeg, mend being undefined).
cc-defs.el (c-version): Update to 5.31.3.
cc-defs.el: [Supersedes patch V1.38]: (top level): Check for a buggy
font-lock-compile-keywords ONLY in XEmacs. GNU Emacs 22 now has a check
which would throw an error here.
cc-engine.el (c-beginning-of-statement-1): Clarify doc-string and
comments. Distinguish real labels ("case 1:" or "foo:") from non-labels
("public:").
cc-engine.el (c-after-change-check-<>-operators): Remove save-match-data,
reversing change for V1.45. save-match-data is now in c-after-change.
cc-engine.el (c-forward-objc-directive): Replace c-forward-token-2 with
crude coding; c-f-t-2 doesn't move over a token at EOB. Objc Mode was
hanging after typing, e.g., "@implementation".
cc-langs.el (c-filter-ops): Made it available at runtime too to work when
`c-make-init-lang-vars-fun' needs to evaluate from source.
cc-langs.el (c-make-init-lang-vars-fun): Improved the error message when
there's an evaluation error to show whether it's loaded from source or
not.
(c-mode-menu): Add menu items for Electric Mode and Subword Mode.
cc-mode.el (c-after-change): Protect the match data with save-match-data.
It was getting corrupted by c-after-change-check-<>-operators.
cc-mode.el: File Local variables: Solve the problem where both `mode' and
c-file-offsets are specified: `mode' will overwrite c-f-o's settings:
(c-remove-any-local-eval-or-mode-variables): new function.
(c-postprocess-file-styles): call the above new function, within
c-tentative-buffer-change, to splat `mode' and `eval' before the second
hack-local-variables.
