7224 (make_binding_level): Use ggc_alloc_cleared or memset.
7225 (lookup_tag): Remove struct binding_level* parameter. All
7226 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
7227 current_binding_level->tags if asked for thislevel_only or if
7228 we might have to diagnose "struct foo; union foo;"
7229 (pushlevel): Ignore argument. Do not push another binding
7230 level on the transition from the parameters to the top level
7231 of the function body; just tweak the flags and proceed.
7232 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
7233 a function body, separate the parameter list from the
7234 top-level local variables.
7235 (set_block): Do nothing.

7237 shadowed_tags if necessary.

7247 empty functions. Otherwise, don't call poplevel.
7249 * c-common.c (shadow_warning): MANDATORY argument is no longer
7250 necessary. Always use plain warning.

7279 (c_print_identifier): Update to match changes to struct
7281 (poplevel): Delete #if 0 block. Make externals invisible
7282 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7283 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7284 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7285 (duplicate-decls): For real parm decl after a forward decl,
7286 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7287 foo(...) { } with only a warning. Say whether a previous
7288 declaration was implicit.
7289 (warn_if_shadowing): Now handles all shadowing, not just
7290 local-over-local. Clarify comments.
7291 (pushdecl): Rewritten. There is no longer a distinction
7292 between global and local symbol values; they're all
7293 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7294 DECL_EXTERNAL decls, and use any_external_decl to check
7295 against previous externals. Kill #if 0 blocks. Don't
7296 tolerate error_mark_node being NULL.

7298 Objective C (the only user) needs.
7299 (pushdecl_function_level): New function.
7300 (implicitly_declare): Create ordinary decls with

7321 IDENTIFIER_GLOBAL_VALUE.
