9141 we might have to diagnose "struct foo; union foo;"
9142 (pushlevel): Ignore argument. Do not push another binding
9143 level on the transition from the parameters to the top level
9144 of the function body; just tweak the flags and proceed.

9147 top-level local variables.
9148 (set_block): Do nothing.

9192 (c_print_identifier): Update to match changes to struct
9194 (poplevel): Delete #if 0 block. Make externals invisible
9195 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9196 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9197 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9198 (duplicate-decls): For real parm decl after a forward decl,
9199 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9200 foo(...) { } with only a warning. Say whether a previous
9201 declaration was implicit.
9202 (warn_if_shadowing): Now handles all shadowing, not just
9203 local-over-local. Clarify comments.
9204 (pushdecl): Rewritten. There is no longer a distinction
9205 between global and local symbol values; they're all
9206 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9207 DECL_EXTERNAL decls, and use any_external_decl to check
9208 against previous externals. Kill #if 0 blocks. Don't
9209 tolerate error_mark_node being NULL.

9211 Objective C (the only user) needs.
9212 (pushdecl_function_level): New function.
9213 (implicitly_declare): Create ordinary decls with
9214 C_DECL_IMPLICIT set. Recycle old decls, however they got

9229 from build_external_ref.

9234 IDENTIFIER_GLOBAL_VALUE.
