9993 current_binding_level->tags if asked for thislevel_only or if
9994 we might have to diagnose "struct foo; union foo;"
9995 (pushlevel): Ignore argument. Do not push another binding
9996 level on the transition from the parameters to the top level
9997 of the function body; just tweak the flags and proceed.

10000 top-level local variables.

10045 (c_print_identifier): Update to match changes to struct
10047 (poplevel): Delete #if 0 block. Make externals invisible
10048 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10049 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10050 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10051 (duplicate-decls): For real parm decl after a forward decl,
10052 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10056 local-over-local. Clarify comments.

10064 Objective C (the only user) needs.
10065 (pushdecl_function_level): New function.
