9350 we might have to diagnose "struct foo; union foo;"
9351 (pushlevel): Ignore argument. Do not push another binding
9352 level on the transition from the parameters to the top level
9353 of the function body; just tweak the flags and proceed.

9356 top-level local variables.

9359 shadowed_tags if necessary.

9369 empty functions. Otherwise, don't call poplevel.

9401 (c_print_identifier): Update to match changes to struct
9403 (poplevel): Delete #if 0 block. Make externals invisible
9404 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9405 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9406 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9407 (duplicate-decls): For real parm decl after a forward decl,
9408 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9409 foo(...) { } with only a warning. Say whether a previous
9410 declaration was implicit.
9411 (warn_if_shadowing): Now handles all shadowing, not just
9412 local-over-local. Clarify comments.
9413 (pushdecl): Rewritten. There is no longer a distinction
9414 between global and local symbol values; they're all
9415 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9416 DECL_EXTERNAL decls, and use any_external_decl to check
9417 against previous externals. Kill #if 0 blocks. Don't
9418 tolerate error_mark_node being NULL.

9420 Objective C (the only user) needs.
9421 (pushdecl_function_level): New function.
9422 (implicitly_declare): Create ordinary decls with
9423 C_DECL_IMPLICIT set. Recycle old decls, however they got
9425 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
9426 for C_DECL_INVISIBLE symbols.
