    * tree-core.h (builtin_info, builtin_info_type): Turn from
    an object with two arrays into an array of an object with
    decl and two flags, implicit_p and declared_p.
    * tree.h (builtin_decl_explicit, builtin_decl_implicit,
    set_builtin_decl, set_builtin_decl_implicit_p,
    builtin_decl_explicit_p, builtin_decl_implicit_p): Adjust.
    (set_builtin_decl_declared_p, builtin_decl_declared_p): New functions.
    * builtins.c (builtin_info): Adjust.
    * gimplify.c (gimplify_addr_expr): References to builtins
    that have been declared by the user makes them eligible for
    use by the compiler.  Call set_builtin_decl_implicit_p on them.

    c/
    * c-decl.c (merge_decls): Call set_builtin_decl_declared_p
    for builtins the user declared correctly.

    cp/
