1929 (make_binding_level): Use ggc_alloc_cleared or memset.
1930 (lookup_tag): Remove struct binding_level* parameter. All

1932 current_binding_level->tags if asked for thislevel_only or if
1933 we might have to diagnose "struct foo; union foo;"
1934 (pushlevel): Ignore argument. Do not push another binding
1935 level on the transition from the parameters to the top level
1936 of the function body; just tweak the flags and proceed.

1938 a function body, separate the parameter list from the
1939 top-level local variables.
1940 (set_block): Do nothing.

1984 (c_print_identifier): Update to match changes to struct
1986 (poplevel): Delete #if 0 block. Make externals invisible
1987 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1988 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1989 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1990 (duplicate-decls): For real parm decl after a forward decl,
1991 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1992 foo(...) { } with only a warning. Say whether a previous
1993 declaration was implicit.
1994 (warn_if_shadowing): Now handles all shadowing, not just
1995 local-over-local. Clarify comments.
1996 (pushdecl): Rewritten. There is no longer a distinction
1997 between global and local symbol values; they're all
1998 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1999 DECL_EXTERNAL decls, and use any_external_decl to check
2000 against previous externals. Kill #if 0 blocks. Don't
2001 tolerate error_mark_node being NULL.

2003 Objective C (the only user) needs.
2004 (pushdecl_function_level): New function.
2005 (implicitly_declare): Create ordinary decls with
