11400 current_binding_level->tags if asked for thislevel_only or if
11401 we might have to diagnose "struct foo; union foo;"
11402 (pushlevel): Ignore argument. Do not push another binding
11403 level on the transition from the parameters to the top level
11404 of the function body; just tweak the flags and proceed.

11406 a function body, separate the parameter list from the
11407 top-level local variables.

11420 empty functions. Otherwise, don't call poplevel.

11451 (clone_underlying type): Split out of pushdecl.
11452 (c_print_identifier): Update to match changes to struct
11454 (poplevel): Delete #if 0 block. Make externals invisible
11455 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11456 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11457 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11458 (duplicate-decls): For real parm decl after a forward decl,
11459 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
11460 foo(...) { } with only a warning. Say whether a previous

11462 (warn_if_shadowing): Now handles all shadowing, not just
11463 local-over-local. Clarify comments.
11464 (pushdecl): Rewritten. There is no longer a distinction
11465 between global and local symbol values; they're all
11466 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
11467 DECL_EXTERNAL decls, and use any_external_decl to check
11468 against previous externals. Kill #if 0 blocks. Don't
11469 tolerate error_mark_node being NULL.
11470 (pushdecl_top_level): Handle only those cases which
11471 Objective C (the only user) needs.
11472 (pushdecl_function_level): New function.
11473 (implicitly_declare): Create ordinary decls with
