10297 we might have to diagnose "struct foo; union foo;"
10298 (pushlevel): Ignore argument. Do not push another binding
10299 level on the transition from the parameters to the top level
10300 of the function body; just tweak the flags and proceed.

10347 (clone_underlying type): Split out of pushdecl.
10348 (c_print_identifier): Update to match changes to struct
10350 (poplevel): Delete #if 0 block. Make externals invisible
10351 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10352 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10353 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10354 (duplicate-decls): For real parm decl after a forward decl,
10355 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10356 foo(...) { } with only a warning. Say whether a previous

10358 (warn_if_shadowing): Now handles all shadowing, not just
10359 local-over-local. Clarify comments.
10360 (pushdecl): Rewritten. There is no longer a distinction
10361 between global and local symbol values; they're all
10362 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10363 DECL_EXTERNAL decls, and use any_external_decl to check
10364 against previous externals. Kill #if 0 blocks. Don't
10365 tolerate error_mark_node being NULL.
10366 (pushdecl_top_level): Handle only those cases which
10367 Objective C (the only user) needs.
10368 (pushdecl_function_level): New function.
10369 (implicitly_declare): Create ordinary decls with
10370 C_DECL_IMPLICIT set. Recycle old decls, however they got
