12754 we might have to diagnose "struct foo; union foo;"
12755 (pushlevel): Ignore argument. Do not push another binding
12756 level on the transition from the parameters to the top level
12757 of the function body; just tweak the flags and proceed.

12760 top-level local variables.

12805 (c_print_identifier): Update to match changes to struct
12807 (poplevel): Delete #if 0 block. Make externals invisible
12808 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12809 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12810 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12811 (duplicate-decls): For real parm decl after a forward decl,
12812 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

12816 local-over-local. Clarify comments.

12818 between global and local symbol values; they're all
12819 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12820 DECL_EXTERNAL decls, and use any_external_decl to check
12821 against previous externals. Kill #if 0 blocks. Don't
12822 tolerate error_mark_node being NULL.
12823 (pushdecl_top_level): Handle only those cases which
12824 Objective C (the only user) needs.
12825 (pushdecl_function_level): New function.
12826 (implicitly_declare): Create ordinary decls with
