3573 (make_binding_level): Use ggc_alloc_cleared or memset.
3574 (lookup_tag): Remove struct binding_level* parameter. All

3576 current_binding_level->tags if asked for thislevel_only or if
3577 we might have to diagnose "struct foo; union foo;"
3578 (pushlevel): Ignore argument. Do not push another binding
3579 level on the transition from the parameters to the top level
3580 of the function body; just tweak the flags and proceed.
3581 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
3582 a function body, separate the parameter list from the
3583 top-level local variables.
3584 (set_block): Do nothing.

3586 shadowed_tags if necessary.

3590 an older decl in the same binding level.

3593 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
3594 (start_function): Don't set subblocks_tag_transparent.

3596 empty functions. Otherwise, don't call poplevel.
3598 * c-common.c (shadow_warning): MANDATORY argument is no longer
3599 necessary. Always use plain warning.
3600 * c-common.h: Update to match.

3627 (clone_underlying type): Split out of pushdecl.
3628 (c_print_identifier): Update to match changes to struct
3630 (poplevel): Delete #if 0 block. Make externals invisible
3631 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3632 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3633 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3634 (duplicate-decls): For real parm decl after a forward decl,
3635 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
3636 foo(...) { } with only a warning. Say whether a previous
3637 declaration was implicit.
3638 (warn_if_shadowing): Now handles all shadowing, not just
3639 local-over-local. Clarify comments.
3640 (pushdecl): Rewritten. There is no longer a distinction
3641 between global and local symbol values; they're all
3642 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
3643 DECL_EXTERNAL decls, and use any_external_decl to check
3644 against previous externals. Kill #if 0 blocks. Don't
3645 tolerate error_mark_node being NULL.
3646 (pushdecl_top_level): Handle only those cases which
3647 Objective C (the only user) needs.
3648 (pushdecl_function_level): New function.
3649 (implicitly_declare): Create ordinary decls with
3650 C_DECL_IMPLICIT set. Recycle old decls, however they got
3652 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
3653 for C_DECL_INVISIBLE symbols.
