1925 (make_binding_level): Use ggc_alloc_cleared or memset.
1926 (lookup_tag): Remove struct binding_level* parameter. All
1927 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1928 current_binding_level->tags if asked for thislevel_only or if
1929 we might have to diagnose "struct foo; union foo;"
1930 (pushlevel): Ignore argument. Do not push another binding
1931 level on the transition from the parameters to the top level
1932 of the function body; just tweak the flags and proceed.
1933 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1934 a function body, separate the parameter list from the
1935 top-level local variables.
1936 (set_block): Do nothing.

1938 shadowed_tags if necessary.

1980 (c_print_identifier): Update to match changes to struct
1982 (poplevel): Delete #if 0 block. Make externals invisible
1983 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1984 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1985 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1986 (duplicate-decls): For real parm decl after a forward decl,
1987 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1988 foo(...) { } with only a warning. Say whether a previous
1989 declaration was implicit.
1990 (warn_if_shadowing): Now handles all shadowing, not just
1991 local-over-local. Clarify comments.
1992 (pushdecl): Rewritten. There is no longer a distinction
1993 between global and local symbol values; they're all
1994 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1995 DECL_EXTERNAL decls, and use any_external_decl to check
1996 against previous externals. Kill #if 0 blocks. Don't
1997 tolerate error_mark_node being NULL.

1999 Objective C (the only user) needs.
2000 (pushdecl_function_level): New function.
2001 (implicitly_declare): Create ordinary decls with

2022 IDENTIFIER_GLOBAL_VALUE.
