933 we might have to diagnose "struct foo; union foo;"
934 (pushlevel): Ignore argument. Do not push another binding
935 level on the transition from the parameters to the top level
936 of the function body; just tweak the flags and proceed.
937 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
938 a function body, separate the parameter list from the
939 top-level local variables.
940 (set_block): Do nothing.
941 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
942 shadowed_tags if necessary.

946 an older decl in the same binding level.

949 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
950 (start_function): Don't set subblocks_tag_transparent.
951 (finish_function): Fix up the binding_level stack for totally
952 empty functions. Otherwise, don't call poplevel.

955 necessary. Always use plain warning.
956 * c-common.h: Update to match.
958 * cfglayout.c (scope_to_insns_initialize): Clear block when we
959 hit the FUNCTION_DECL.

986 (poplevel): Delete #if 0 block. Make externals invisible
987 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
988 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
989 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
990 (duplicate-decls): For real parm decl after a forward decl,
991 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
992 foo(...) { } with only a warning. Say whether a previous
993 declaration was implicit.
994 (warn_if_shadowing): Now handles all shadowing, not just
995 local-over-local. Clarify comments.
996 (pushdecl): Rewritten. There is no longer a distinction
997 between global and local symbol values; they're all

999 DECL_EXTERNAL decls, and use any_external_decl to check
1000 against previous externals. Kill #if 0 blocks. Don't
1001 tolerate error_mark_node being NULL.

1018 global_binding_level in extremis.
1020 * c-typeck.c (undeclared_variable): New static function, split
1021 from build_external_ref.

1026 IDENTIFIER_GLOBAL_VALUE.
