10161 we might have to diagnose "struct foo; union foo;"
10162 (pushlevel): Ignore argument. Do not push another binding
10163 level on the transition from the parameters to the top level
10164 of the function body; just tweak the flags and proceed.

10167 top-level local variables.

10212 (c_print_identifier): Update to match changes to struct
10214 (poplevel): Delete #if 0 block. Make externals invisible
10215 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10216 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10217 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10218 (duplicate-decls): For real parm decl after a forward decl,
10219 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10220 foo(...) { } with only a warning. Say whether a previous

10223 local-over-local. Clarify comments.

10225 between global and local symbol values; they're all
10226 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10227 DECL_EXTERNAL decls, and use any_external_decl to check
10228 against previous externals. Kill #if 0 blocks. Don't
10229 tolerate error_mark_node being NULL.

10231 Objective C (the only user) needs.
10232 (pushdecl_function_level): New function.
10233 (implicitly_declare): Create ordinary decls with
