10157 we might have to diagnose "struct foo; union foo;"
10158 (pushlevel): Ignore argument. Do not push another binding
10159 level on the transition from the parameters to the top level
10160 of the function body; just tweak the flags and proceed.

10208 (c_print_identifier): Update to match changes to struct
10210 (poplevel): Delete #if 0 block. Make externals invisible
10211 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10212 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10213 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10214 (duplicate-decls): For real parm decl after a forward decl,
10215 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10219 local-over-local. Clarify comments.

10221 between global and local symbol values; they're all
10222 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10223 DECL_EXTERNAL decls, and use any_external_decl to check
10224 against previous externals. Kill #if 0 blocks. Don't
10225 tolerate error_mark_node being NULL.

10227 Objective C (the only user) needs.
10228 (pushdecl_function_level): New function.
10229 (implicitly_declare): Create ordinary decls with
