9606 we might have to diagnose "struct foo; union foo;"
9607 (pushlevel): Ignore argument. Do not push another binding
9608 level on the transition from the parameters to the top level
9609 of the function body; just tweak the flags and proceed.

9612 top-level local variables.

9657 (c_print_identifier): Update to match changes to struct
9659 (poplevel): Delete #if 0 block. Make externals invisible
9660 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9661 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9662 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9663 (duplicate-decls): For real parm decl after a forward decl,
9664 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9665 foo(...) { } with only a warning. Say whether a previous
9666 declaration was implicit.
9667 (warn_if_shadowing): Now handles all shadowing, not just
9668 local-over-local. Clarify comments.
9669 (pushdecl): Rewritten. There is no longer a distinction
9670 between global and local symbol values; they're all
9671 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9672 DECL_EXTERNAL decls, and use any_external_decl to check
9673 against previous externals. Kill #if 0 blocks. Don't
9674 tolerate error_mark_node being NULL.

9676 Objective C (the only user) needs.
9677 (pushdecl_function_level): New function.
9678 (implicitly_declare): Create ordinary decls with

9699 IDENTIFIER_GLOBAL_VALUE.
