From 165cfed262ccccf6d6790910f5dafc2af3ac5383 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 10 Sep 2003 09:06:37 +0000 Subject: (POINTER): Remove. All uses changed to void *. (obstack_alloc_failed_handler, CALL_CHUNKFUN, CALL_FREEFUN, _obstack_begin, _obstack_begin_1, _obstack_allocated_p) (defined __STDC__ && __STDC__)]: Remove nonprototyped code. Include unconditionally. (_obstack_begin, _obstack_begin_1, _obstack_newchunk, _obstack_allocated_p, _obstack_free, obstack_free, _obstack_memory_used, print_and_abort): Define using prototypes. (obstack_1grow, obstack_1grow_fast, obstack_alloc, obstack_base, obstack_blank, obstack_blank_fast, obstack_copy, obstack_copy0, obstack_finish, obstack_grow, obstack_grow0, obstack_make_room, obstack_next_free, obstack_object_size, obstack_room) [0]: Remove unused, unprototyped code. --- lib/obstack.c | 233 +++++++--------------------------------------------------- 1 file changed, 25 insertions(+), 208 deletions(-) (limited to 'lib') diff --git a/lib/obstack.c b/lib/obstack.c index 17eb986fa..705c65d4a 100644 --- a/lib/obstack.c +++ b/lib/obstack.c @@ -1,5 +1,8 @@ /* obstack.c - subroutines used implicitly by object stack macros - Copyright (C) 1988-1994, 1996-1999, 2000-2002 Free Software Foundation, Inc. + + Copyright (C) 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1996, 1997, + 1998, 1999, 2000, 2001, 2002, 2003 Free Software Foundation, Inc. + This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2, or (at your option) @@ -49,12 +52,6 @@ #ifndef ELIDE_CODE -# if defined __STDC__ && __STDC__ -# define POINTER void * -# else -# define POINTER char * -# endif - /* Determine default alignment. */ struct fooalign {char x; double d;}; # define DEFAULT_ALIGNMENT \ @@ -80,18 +77,11 @@ union fooround {long x; double d;}; abort gracefully or use longjump - but shouldn't return.
