3810 we might have to diagnose "struct foo; union foo;"
3811 (pushlevel): Ignore argument. Do not push another binding
3812 level on the transition from the parameters to the top level
3813 of the function body; just tweak the flags and proceed.

3815 a function body, separate the parameter list from the
3816 top-level local variables.
3817 (set_block): Do nothing.

3861 (c_print_identifier): Update to match changes to struct
3863 (poplevel): Delete #if 0 block. Make externals invisible
3864 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3865 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3866 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3867 (duplicate-decls): For real parm decl after a forward decl,
3868 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
3869 foo(...) { } with only a warning. Say whether a previous
3870 declaration was implicit.
3871 (warn_if_shadowing): Now handles all shadowing, not just
3872 local-over-local. Clarify comments.
3873 (pushdecl): Rewritten. There is no longer a distinction
3874 between global and local symbol values; they're all
3875 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
3876 DECL_EXTERNAL decls, and use any_external_decl to check
3877 against previous externals. Kill #if 0 blocks. Don't
3878 tolerate error_mark_node being NULL.

3880 Objective C (the only user) needs.
3881 (pushdecl_function_level): New function.
3882 (implicitly_declare): Create ordinary decls with

3903 IDENTIFIER_GLOBAL_VALUE.
