10060 current_binding_level->tags if asked for thislevel_only or if
10061 we might have to diagnose "struct foo; union foo;"
10062 (pushlevel): Ignore argument. Do not push another binding
10063 level on the transition from the parameters to the top level
10064 of the function body; just tweak the flags and proceed.

10067 top-level local variables.

10111 (clone_underlying type): Split out of pushdecl.
10112 (c_print_identifier): Update to match changes to struct
10114 (poplevel): Delete #if 0 block. Make externals invisible
10115 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10116 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10117 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10118 (duplicate-decls): For real parm decl after a forward decl,
10119 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10120 foo(...) { } with only a warning. Say whether a previous

10122 (warn_if_shadowing): Now handles all shadowing, not just
10123 local-over-local. Clarify comments.
10124 (pushdecl): Rewritten. There is no longer a distinction
10125 between global and local symbol values; they're all
10126 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10127 DECL_EXTERNAL decls, and use any_external_decl to check
10128 against previous externals. Kill #if 0 blocks. Don't
10129 tolerate error_mark_node being NULL.
10130 (pushdecl_top_level): Handle only those cases which
10131 Objective C (the only user) needs.
10132 (pushdecl_function_level): New function.
10133 (implicitly_declare): Create ordinary decls with

10149 from build_external_ref.

10154 IDENTIFIER_GLOBAL_VALUE.
