10104 current_binding_level->tags if asked for thislevel_only or if
10105 we might have to diagnose "struct foo; union foo;"
10106 (pushlevel): Ignore argument. Do not push another binding
10107 level on the transition from the parameters to the top level
10108 of the function body; just tweak the flags and proceed.

10110 a function body, separate the parameter list from the
10111 top-level local variables.

10155 (clone_underlying type): Split out of pushdecl.
10156 (c_print_identifier): Update to match changes to struct
10158 (poplevel): Delete #if 0 block. Make externals invisible
10159 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10160 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10161 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10162 (duplicate-decls): For real parm decl after a forward decl,
10163 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10164 foo(...) { } with only a warning. Say whether a previous

10167 local-over-local. Clarify comments.
10168 (pushdecl): Rewritten. There is no longer a distinction
10169 between global and local symbol values; they're all
10170 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10171 DECL_EXTERNAL decls, and use any_external_decl to check
10172 against previous externals. Kill #if 0 blocks. Don't
10173 tolerate error_mark_node being NULL.
10174 (pushdecl_top_level): Handle only those cases which
10175 Objective C (the only user) needs.
10176 (pushdecl_function_level): New function.
10177 (implicitly_declare): Create ordinary decls with
10178 C_DECL_IMPLICIT set. Recycle old decls, however they got

10198 IDENTIFIER_GLOBAL_VALUE.
