+       * vasnprintf.c (local_wcslen): New function, for Solaris 2.5.1.
+       (vasnprintf): Use it instead of wcslen.

        * stdbool_.h (_Bool): Undo last change; instead use a negative enum
        value to ensure that _Bool promotes to int. Use #define for _Bool when
        using the Solaris C compiler. Adds comments suggested by Paul Eggert.
