7794 current_binding_level->tags if asked for thislevel_only or if
7795 we might have to diagnose "struct foo; union foo;"
7796 (pushlevel): Ignore argument. Do not push another binding
7797 level on the transition from the parameters to the top level
7798 of the function body; just tweak the flags and proceed.

7848 (poplevel): Delete #if 0 block. Make externals invisible
7849 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7850 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7851 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7852 (duplicate-decls): For real parm decl after a forward decl,
7853 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

7857 local-over-local. Clarify comments.

7865 Objective C (the only user) needs.
