10131 current_binding_level->tags if asked for thislevel_only or if
10132 we might have to diagnose "struct foo; union foo;"
10133 (pushlevel): Ignore argument. Do not push another binding
10134 level on the transition from the parameters to the top level
10135 of the function body; just tweak the flags and proceed.

10138 top-level local variables.

10183 (c_print_identifier): Update to match changes to struct
10185 (poplevel): Delete #if 0 block. Make externals invisible
10186 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10187 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10188 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10189 (duplicate-decls): For real parm decl after a forward decl,
10190 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10191 foo(...) { } with only a warning. Say whether a previous

10194 local-over-local. Clarify comments.
10195 (pushdecl): Rewritten. There is no longer a distinction
10196 between global and local symbol values; they're all
10197 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10198 DECL_EXTERNAL decls, and use any_external_decl to check
10199 against previous externals. Kill #if 0 blocks. Don't
10200 tolerate error_mark_node being NULL.
10201 (pushdecl_top_level): Handle only those cases which
10202 Objective C (the only user) needs.
10203 (pushdecl_function_level): New function.
10204 (implicitly_declare): Create ordinary decls with
10205 C_DECL_IMPLICIT set. Recycle old decls, however they got
