10118 current_binding_level->tags if asked for thislevel_only or if
10119 we might have to diagnose "struct foo; union foo;"
10120 (pushlevel): Ignore argument. Do not push another binding
10121 level on the transition from the parameters to the top level
10122 of the function body; just tweak the flags and proceed.

10125 top-level local variables.

10169 (clone_underlying type): Split out of pushdecl.
10170 (c_print_identifier): Update to match changes to struct
10172 (poplevel): Delete #if 0 block. Make externals invisible
10173 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10174 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10175 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10176 (duplicate-decls): For real parm decl after a forward decl,
10177 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10178 foo(...) { } with only a warning. Say whether a previous

10180 (warn_if_shadowing): Now handles all shadowing, not just
10181 local-over-local. Clarify comments.

10183 between global and local symbol values; they're all
10184 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10185 DECL_EXTERNAL decls, and use any_external_decl to check
10186 against previous externals. Kill #if 0 blocks. Don't
10187 tolerate error_mark_node being NULL.
10188 (pushdecl_top_level): Handle only those cases which
10189 Objective C (the only user) needs.
10190 (pushdecl_function_level): New function.
10191 (implicitly_declare): Create ordinary decls with
10192 C_DECL_IMPLICIT set. Recycle old decls, however they got

10212 IDENTIFIER_GLOBAL_VALUE.
