5292 we might have to diagnose "struct foo; union foo;"
5293 (pushlevel): Ignore argument. Do not push another binding
5294 level on the transition from the parameters to the top level
5295 of the function body; just tweak the flags and proceed.

5298 top-level local variables.

5301 shadowed_tags if necessary.

5311 empty functions. Otherwise, don't call poplevel.

5343 (c_print_identifier): Update to match changes to struct
5345 (poplevel): Delete #if 0 block. Make externals invisible
5346 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5347 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5348 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5349 (duplicate-decls): For real parm decl after a forward decl,
5350 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5351 foo(...) { } with only a warning. Say whether a previous
5352 declaration was implicit.
5353 (warn_if_shadowing): Now handles all shadowing, not just
5354 local-over-local. Clarify comments.
5355 (pushdecl): Rewritten. There is no longer a distinction
5356 between global and local symbol values; they're all
5357 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5358 DECL_EXTERNAL decls, and use any_external_decl to check
5359 against previous externals. Kill #if 0 blocks. Don't
5360 tolerate error_mark_node being NULL.

5362 Objective C (the only user) needs.
5363 (pushdecl_function_level): New function.
5364 (implicitly_declare): Create ordinary decls with
5365 C_DECL_IMPLICIT set. Recycle old decls, however they got
5367 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
5368 for C_DECL_INVISIBLE symbols.
5369 (lookup_name_current_level): Likewise. Use chain_member.
