10521 (make_binding_level): Use ggc_alloc_cleared or memset.
10522 (lookup_tag): Remove struct binding_level* parameter. All
10523 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
10524 current_binding_level->tags if asked for thislevel_only or if
10525 we might have to diagnose "struct foo; union foo;"
10526 (pushlevel): Ignore argument. Do not push another binding
10527 level on the transition from the parameters to the top level
10528 of the function body; just tweak the flags and proceed.

10530 a function body, separate the parameter list from the
10531 top-level local variables.

10544 empty functions. Otherwise, don't call poplevel.

10575 (clone_underlying type): Split out of pushdecl.
10576 (c_print_identifier): Update to match changes to struct
10578 (poplevel): Delete #if 0 block. Make externals invisible
10579 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10580 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10581 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10582 (duplicate-decls): For real parm decl after a forward decl,
10583 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10584 foo(...) { } with only a warning. Say whether a previous

10587 local-over-local. Clarify comments.

10589 between global and local symbol values; they're all
10590 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10591 DECL_EXTERNAL decls, and use any_external_decl to check
10592 against previous externals. Kill #if 0 blocks. Don't
10593 tolerate error_mark_node being NULL.
10594 (pushdecl_top_level): Handle only those cases which
10595 Objective C (the only user) needs.
10596 (pushdecl_function_level): New function.
10597 (implicitly_declare): Create ordinary decls with
