7859 we might have to diagnose "struct foo; union foo;"
7860 (pushlevel): Ignore argument. Do not push another binding
7861 level on the transition from the parameters to the top level
7862 of the function body; just tweak the flags and proceed.

7910 (c_print_identifier): Update to match changes to struct
7912 (poplevel): Delete #if 0 block. Make externals invisible
7913 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7914 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7915 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7916 (duplicate-decls): For real parm decl after a forward decl,
7917 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7918 foo(...) { } with only a warning. Say whether a previous
7919 declaration was implicit.

7921 local-over-local. Clarify comments.
7922 (pushdecl): Rewritten. There is no longer a distinction
7923 between global and local symbol values; they're all
7924 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7925 DECL_EXTERNAL decls, and use any_external_decl to check
7926 against previous externals. Kill #if 0 blocks. Don't
7927 tolerate error_mark_node being NULL.

7929 Objective C (the only user) needs.
7930 (pushdecl_function_level): New function.
7931 (implicitly_declare): Create ordinary decls with

7952 IDENTIFIER_GLOBAL_VALUE.
