13361 current_binding_level->tags if asked for thislevel_only or if
13362 we might have to diagnose "struct foo; union foo;"
13363 (pushlevel): Ignore argument. Do not push another binding
13364 level on the transition from the parameters to the top level
13365 of the function body; just tweak the flags and proceed.

13367 a function body, separate the parameter list from the
13368 top-level local variables.

13371 shadowed_tags if necessary.

13381 empty functions. Otherwise, don't call poplevel.

13384 necessary. Always use plain warning.
13385 * c-common.h: Update to match.

13411 (any_external_decl, record_external_decl): New static functions.
13412 (clone_underlying type): Split out of pushdecl.
13413 (c_print_identifier): Update to match changes to struct
13415 (poplevel): Delete #if 0 block. Make externals invisible
13416 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13417 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13418 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13419 (duplicate-decls): For real parm decl after a forward decl,
13420 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
13421 foo(...) { } with only a warning. Say whether a previous
13422 declaration was implicit.
13423 (warn_if_shadowing): Now handles all shadowing, not just
13424 local-over-local. Clarify comments.
13425 (pushdecl): Rewritten. There is no longer a distinction
13426 between global and local symbol values; they're all
13427 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13428 DECL_EXTERNAL decls, and use any_external_decl to check
13429 against previous externals. Kill #if 0 blocks. Don't
13430 tolerate error_mark_node being NULL.
13431 (pushdecl_top_level): Handle only those cases which
13432 Objective C (the only user) needs.
