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

355 a function body, separate the parameter list from the
356 top-level local variables.
357 (set_block): Do nothing.

403 (poplevel): Delete #if 0 block. Make externals invisible
404 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
405 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
406 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
407 (duplicate-decls): For real parm decl after a forward decl,
408 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
409 foo(...) { } with only a warning. Say whether a previous
410 declaration was implicit.
411 (warn_if_shadowing): Now handles all shadowing, not just
412 local-over-local. Clarify comments.
413 (pushdecl): Rewritten. There is no longer a distinction
414 between global and local symbol values; they're all
415 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
416 DECL_EXTERNAL decls, and use any_external_decl to check
417 against previous externals. Kill #if 0 blocks. Don't
418 tolerate error_mark_node being NULL.

420 Objective C (the only user) needs.

426 for C_DECL_INVISIBLE symbols.
427 (lookup_name_current_level): Likewise. Use chain_member.

432 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
433 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.

435 global_binding_level in extremis.
437 * c-typeck.c (undeclared_variable): New static function, split
438 from build_external_ref.
439 (build_external_ref): Use DECL_CONTEXT, not
440 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
