6022 we might have to diagnose "struct foo; union foo;"
6023 (pushlevel): Ignore argument. Do not push another binding
6024 level on the transition from the parameters to the top level
6025 of the function body; just tweak the flags and proceed.

6073 (c_print_identifier): Update to match changes to struct
6075 (poplevel): Delete #if 0 block. Make externals invisible
6076 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6077 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6078 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6079 (duplicate-decls): For real parm decl after a forward decl,
6080 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6081 foo(...) { } with only a warning. Say whether a previous
6082 declaration was implicit.
6083 (warn_if_shadowing): Now handles all shadowing, not just
6084 local-over-local. Clarify comments.
6085 (pushdecl): Rewritten. There is no longer a distinction
6086 between global and local symbol values; they're all
6087 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6088 DECL_EXTERNAL decls, and use any_external_decl to check
6089 against previous externals. Kill #if 0 blocks. Don't
6090 tolerate error_mark_node being NULL.

6092 Objective C (the only user) needs.
6093 (pushdecl_function_level): New function.
6094 (implicitly_declare): Create ordinary decls with

6115 IDENTIFIER_GLOBAL_VALUE.
