(toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
(x_dispatch_event): Declare static only if !USE_GTK && USE_X_TOOLKIT.

defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
* Activate.c (XMenuActivate): Callback's first arg is readonly.
* AddPane.c (XMenuAddPane): Label is readonly. Rename local
to avoid shadowing.
* AddSel.c (XMenuAddSelection): Help arg is readonly. Rename local.
* Create.c (atoi, atof): Remove decls; include <stdlib.h>.
(MAX_INACT_PNUM, TILE_BUF_SIZE): Remove; unused.
(x_get_resource_string): Args are readonly.
(XAllocDisplayColor): colorName is readonly.
(XMenuCreate): def_env is readonly. Remove unused locals. Avoid
"else;".
* Destroy.c (XMenuDestroy): Return void.
* Error.c (XMenuError): Remove const pointer.
* EvHand.c (XMenuEventHandler): Return void.
* FindPane.c, FindSel.c: Include <string.h>.
* InsPane.c (XMenuInsertPane): Rename local to avoid shadowing.
* InsSel.c (XMenuInsertSelection): Likewise.
* Internal.c (toggle_color, BUFFER_SIZE): Remove; unused.
(_XMErrorList): Now const.
(_XMWinQueInit, _XMRecomputeGlobals, _XMTransToOrigin, _XMRefreshPane):
(_XMRefreshSelection): Return void.
(_XMWinQueFlush, _XMRefreshSelection): Rename locals to avoid
shadowing.
(_XMWinQueFlush): Use stack, not heap. Don't use uninitialized var.
* SetAEQ.c (XMenuSetAEQ): Now returns void.
* SetFrz.c (XMenuSetFreeze): Likewise.
* X10.h (XAssoc): Use void * for generic pointer.
* XDelAssoc.c: Include XMenuInt.h rather than duplicating part of it.
* XDestAssoc.c, XMakeAssoc.c: Likewise.
* XDestAssoc.c (XDestroyAssocTable): Return void.
* XMakeAssoc.c (XMakeAssoc): Use void * for generic pointer.
* XMenu.h, XMenuInt.h: Adjust to signature changes. Use const
for pointers to readonly storage.
* insque.c: Include XMenuInt.h, to check our own signature.
(emacs_insque, emacs_remque): Use void * for generic pointers.
* lisp/mail/mailalias.el: Use lexical-binding.
(pattern, mailalias-done): Declare dynamic.
(mail-completion-at-point-function): New function, from mail-complete.
(mail-complete): Use it.
(mail-completion-expand): New function.
(mail-get-names): Use it.
(mail-directory, mail-directory-process, mail-directory-stream):
Don't use `pattern' for lexically bound arg.
* lisp/mail/sendmail.el (mail-mode-map): Use completion-at-point.
(mail-mode): Setup mailalias completion here instead.

up frames from gnus-group-send-queue.
