13208 we might have to diagnose "struct foo; union foo;"
13209 (pushlevel): Ignore argument. Do not push another binding
13210 level on the transition from the parameters to the top level
13211 of the function body; just tweak the flags and proceed.

13214 top-level local variables.

13259 (c_print_identifier): Update to match changes to struct
13261 (poplevel): Delete #if 0 block. Make externals invisible
13262 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13263 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13264 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13265 (duplicate-decls): For real parm decl after a forward decl,
13266 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
13267 foo(...) { } with only a warning. Say whether a previous

13270 local-over-local. Clarify comments.

13272 between global and local symbol values; they're all
13273 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13274 DECL_EXTERNAL decls, and use any_external_decl to check
13275 against previous externals. Kill #if 0 blocks. Don't
13276 tolerate error_mark_node being NULL.

13278 Objective C (the only user) needs.
13279 (pushdecl_function_level): New function.
13280 (implicitly_declare): Create ordinary decls with
