1885 (make_binding_level): Use ggc_alloc_cleared or memset.
1886 (lookup_tag): Remove struct binding_level* parameter. All
1887 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1888 current_binding_level->tags if asked for thislevel_only or if
1889 we might have to diagnose "struct foo; union foo;"
1890 (pushlevel): Ignore argument. Do not push another binding
1891 level on the transition from the parameters to the top level
1892 of the function body; just tweak the flags and proceed.
1893 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1894 a function body, separate the parameter list from the
1895 top-level local variables.
1896 (set_block): Do nothing.
1897 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
1898 shadowed_tags if necessary.

1905 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1906 (start_function): Don't set subblocks_tag_transparent.
1907 (finish_function): Fix up the binding_level stack for totally
1908 empty functions. Otherwise, don't call poplevel.
1910 * c-common.c (shadow_warning): MANDATORY argument is no longer
1911 necessary. Always use plain warning.
1912 * c-common.h: Update to match.

1915 hit the FUNCTION_DECL.
1916 * function.c: Do not create cyclic tree structure.

1940 (c_print_identifier): Update to match changes to struct
1942 (poplevel): Delete #if 0 block. Make externals invisible
1943 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1944 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1945 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1946 (duplicate-decls): For real parm decl after a forward decl,
1947 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1948 foo(...) { } with only a warning. Say whether a previous
1949 declaration was implicit.
1950 (warn_if_shadowing): Now handles all shadowing, not just
1951 local-over-local. Clarify comments.
1952 (pushdecl): Rewritten. There is no longer a distinction
1953 between global and local symbol values; they're all
1954 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1955 DECL_EXTERNAL decls, and use any_external_decl to check
1956 against previous externals. Kill #if 0 blocks. Don't
1957 tolerate error_mark_node being NULL.

1959 Objective C (the only user) needs.
1960 (pushdecl_function_level): New function.
1961 (implicitly_declare): Create ordinary decls with

1982 IDENTIFIER_GLOBAL_VALUE.
