10241 (pushlevel): Ignore argument. Do not push another binding
10242 level on the transition from the parameters to the top level
10243 of the function body; just tweak the flags and proceed.

10291 (c_print_identifier): Update to match changes to struct
10293 (poplevel): Delete #if 0 block. Make externals invisible

10296 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10297 (duplicate-decls): For real parm decl after a forward decl,
10298 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10304 between global and local symbol values; they're all
10305 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10306 DECL_EXTERNAL decls, and use any_external_decl to check
10307 against previous externals. Kill #if 0 blocks. Don't
10308 tolerate error_mark_node being NULL.

10310 Objective C (the only user) needs.
10311 (pushdecl_function_level): New function.
