7853 we might have to diagnose "struct foo; union foo;"
7854 (pushlevel): Ignore argument. Do not push another binding
7855 level on the transition from the parameters to the top level
7856 of the function body; just tweak the flags and proceed.

7904 (c_print_identifier): Update to match changes to struct
7906 (poplevel): Delete #if 0 block. Make externals invisible
7907 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7908 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7909 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7910 (duplicate-decls): For real parm decl after a forward decl,
7911 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7912 foo(...) { } with only a warning. Say whether a previous
7913 declaration was implicit.
7914 (warn_if_shadowing): Now handles all shadowing, not just
7915 local-over-local. Clarify comments.
7916 (pushdecl): Rewritten. There is no longer a distinction
7917 between global and local symbol values; they're all
7918 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7919 DECL_EXTERNAL decls, and use any_external_decl to check
7920 against previous externals. Kill #if 0 blocks. Don't
7921 tolerate error_mark_node being NULL.

7923 Objective C (the only user) needs.
7924 (pushdecl_function_level): New function.
7925 (implicitly_declare): Create ordinary decls with

7946 IDENTIFIER_GLOBAL_VALUE.
