* 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.
