10148 we might have to diagnose "struct foo; union foo;"
10149 (pushlevel): Ignore argument. Do not push another binding
10150 level on the transition from the parameters to the top level
10151 of the function body; just tweak the flags and proceed.

10199 (c_print_identifier): Update to match changes to struct
10201 (poplevel): Delete #if 0 block. Make externals invisible
10202 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10203 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10204 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10205 (duplicate-decls): For real parm decl after a forward decl,
10206 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10216 tolerate error_mark_node being NULL.

10218 Objective C (the only user) needs.
10219 (pushdecl_function_level): New function.
10220 (implicitly_declare): Create ordinary decls with
