10066 current_binding_level->tags if asked for thislevel_only or if
10067 we might have to diagnose "struct foo; union foo;"
10068 (pushlevel): Ignore argument. Do not push another binding
10069 level on the transition from the parameters to the top level
10070 of the function body; just tweak the flags and proceed.

10073 top-level local variables.

10117 (clone_underlying type): Split out of pushdecl.
10118 (c_print_identifier): Update to match changes to struct
10120 (poplevel): Delete #if 0 block. Make externals invisible
10121 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10122 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10123 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10124 (duplicate-decls): For real parm decl after a forward decl,
10125 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10126 foo(...) { } with only a warning. Say whether a previous

10129 local-over-local. Clarify comments.
10130 (pushdecl): Rewritten. There is no longer a distinction
10131 between global and local symbol values; they're all
10132 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10133 DECL_EXTERNAL decls, and use any_external_decl to check
10134 against previous externals. Kill #if 0 blocks. Don't
10135 tolerate error_mark_node being NULL.
10136 (pushdecl_top_level): Handle only those cases which
10137 Objective C (the only user) needs.
10138 (pushdecl_function_level): New function.
10139 (implicitly_declare): Create ordinary decls with
