lisp/progmodes/cc-subword.el, lisp/progmodes/cc-vars.el: Mark these files with
a `lexical-binding' setting in line 1.
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
variables, `last' and `intermediate'.

string with the more precise one from stand-alone CC Mode.

leading _.
The binary uses the 'seccomp' helper library. The library isn't
needed to load the generated Secure Computing filter.
* configure.ac: Check for 'seccomp' header and library.
* lib-src/seccomp-filter.c: New helper binary to generate a generic
Secure Computing filter for GNU/Linux.
* lib-src/Makefile.in (DONT_INSTALL): Add 'seccomp-filter' helper
binary if possible.
(all): Add Secure Computing filter file if possible.
(seccomp-filter$(EXEEXT)): Compile helper binary.
(seccomp-filter.bpf seccomp-filter.pfc): Generate filter files.
* test/src/emacs-tests.el (emacs-tests/seccomp/allows-stdout)
(emacs-tests/seccomp/forbids-subprocess): New unit tests.
* test/Makefile.in (src/emacs-tests.log): Add dependency on the helper
binary.
When passing this option on GNU/Linux, Emacs installs a Secure
Computing kernel system call filter. See Bug#45198.
* configure.ac: Check for seccomp header.
* src/emacs.c (usage_message): Document --seccomp option.
(emacs_seccomp): New wrapper for 'seccomp' syscall.
(load_seccomp, maybe_load_seccomp): New helper functions.
(main): Potentially load seccomp filters during startup.
(standard_args): Add --seccomp option.
* lisp/startup.el (command-line): Detect and ignore --seccomp option.
* test/src/emacs-tests.el (emacs-tests/seccomp/absent-file)
(emacs-tests/seccomp/empty-file)
(emacs-tests/seccomp/file-too-large)
(emacs-tests/seccomp/invalid-file-size): New unit tests.
(emacs-tests--with-temp-file): New helper macro.
* etc/NEWS: Document new --seccomp option.
Edebug doesn't deal well with backtracking out of definitions, see
Bug#41988. Rather than trying to support this rare situation (e.g. by
implementing a multipass parser), prevent it by adding an implicit
gate.
* lisp/emacs-lisp/edebug.el (edebug--match-&-spec-op): Disable
backtracking when hitting a &define keyword.
* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests-duplicate-&define): New unit test.
(edebug-tests--duplicate-&define): New helper macro.
* doc/lispref/edebug.texi (Backtracking): Mention &define in the list
of constructs that disable backtracking.
* etc/NEWS: Document new behavior.
* lisp/net/tramp.el:
* lisp/net/tramp-sh.el: Use (eq system-type 'windows-nt) where appropriate.
(tramp-completion-function-alist-ssh): Fix location of files on W32.
* lisp/net/tramp.el (tramp-completion-file-name-regexp-simplified)
(tramp-completion-file-name-regexp-separate): Fix W32 hostname/method
completion for simplified and separate syntaxes (same as the previous change
to default syntax).

If a Flymake backend calls a "stale" report function,
flymake--handle-report might be called for a backend function that is
no longer in the flymake--backend-state hash table. This patch makes
that erroneous situation slightly more explicit.
* lisp/progmodes/flymake.el (flymake--handle-report): Improve
error reporting.
Make the function correctly recognize a brace block preceded by an
introductory line without a parameter list.
* lisp/progmodes/cc-cmds.el (c-where-wrt-brace-contruct): Reintroduce the use
of c-beginning-of-decl-1, which was removed some weeks ago, in place of a
c-syntactic-skip-backward. Reformulate the code generally.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Don't
perform incorrect optimisations when a condition-case variable shadows
another lexical variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
New test case.
These changes allow all bytecomp-tests to be run interactively.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp--with-warning-test)
(bytecomp--define-warning-file-test): Interpret any space in the
pattern as arbitrary whitespace to tolerate line breaks.
Don't abuse the expected-failure mechanism when checking
for the expected absense of a warning.
(bytecomp/*.el): Rewrite patterns to work with line breaks
in the middle.
Now all test cases are run with both lexical and dynamic binding
where applicable, comparing interpreted against compiled results.
Previously, almost all tests were only run with dynamic binding
which was definitely not intended.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Rename to bytecomp-tests--test-cases.
(bytecomp-check-1, bytecomp-explain-1, bytecomp-tests)
(bytecomp-lexbind-tests, bytecomp-lexbind-check-1)
(bytecomp-lexbind-explain-1): Remove.
(bytecomp-tests--eval-interpreted, bytecomp-tests--eval-compiled)
(bytecomp-tests-lexbind, bytecomp-tests-dynbind)
(bytecomp-tests--test-cases-lexbind-only): New.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Recognise
`condition-case` handlers as being in the tail position.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Extend test.
* lisp/net/tramp.el (tramp-completion-file-name-regexp-default):
Handle volume letter being added to paths for file name completion on W32
systems. This fixes hostname (and method) autocomplete on W32.

Use #' to quote function names to get better compiler diagnostics.
Wrap some lines to avoid arguments "hidden" in positions that are easy
to misread.
Prefix unused arguments with a semi-colon to silence compiler warnings.
Fix a few comments that used ;;; even though they were not headings.
(vhdl-emacs-21): Delete variable.
Replace all uses with (not (featurep 'xemacs)) instead since `vhdl-mode`
has been incompatible with Emacs<21 for more than 10 years already.
(vhdl-prepare-search-1): Add Edebug declaration.
(vhdl-prepare-search-2): Add Edebug declaration and use
`with-syntax-table`.
(vhdl-visit-file): Add Edebug and indentation declaration.
Move the bulk of the code to a function for easier debugging.
(vhdl--visit-file): New function extracted from `vhdl-visit-file`.
Be careful not to modify syntax tables in unrelated buffers.
(vhdl-speedbar-refresh): Remove unused var `pos`.
(vhdl-backward-sexp): Remove unused var `last-forward`.
(vhdl-electric-tab, vhdl-minibuffer-tab, vhdl-line-expand):
Rename arg to avoid conflict with the `prefix-arg`
global variable.
(vhdl-align-region-1): Remove unused var `indent`.
(vhdl-character-to-event): Actually give a body to that poor function.
(vhdl-template-context): Remove unused vars `entity-exists` and `string`.
(vhdl-template-group): Remove unused var `start`.
(vhdl-template-argument-list): Remove unused var `start`.

(vhdl-port-paste-testbench): Remove unused var `source-buffer`.
(vhdl-hs-minor-mode): Declare function `hs-hide-all`.
(vhdl-get-hierarchy): Rename arguments `ent-alist`, `conf-alist`, and
`conf-key` and bind those dynamically scoped var via `let` instead
since arguments can't be dynamically scoped.
(vhdl-speedbar-insert-hierarchy, vhdl-compose-configuration-architecture):
Same thing with arguments `ent-alist` and `conf-alist`.
(vhdl-cache-version): Declare variable.
(speedbar-expand-line, speedbar-edit-line): Declare functions.
(vhdl-speedbar-update-current-unit): Declare before first use.
