-       inttostr: simplify by removing unnecessary redundancy
-       * lib/anytostr.c: Don't include verify.h.
-       (anytostr): Don't verify that TYPE_SIGNED (inttype) equals
-       inttype_is_signed.  Instead, use TYPE_SIGNED (inttype) directly.
-       This removes the need for inttype_is_signed, which was put in to
-       suppress some GCC warnings about conversions.  This rewrite should
-       also suppress those warnings.
-       * lib/imaxtostr.c (inttype_is_signed): Remove; no longer needed.
-       * lib/inttostr.c, lib/offtostr.c, lib/uinttostr.c, lib/umaxtostr.c:
-       Likewise.
-       * modules/inttostr (Depends-on): Remove 'verify'.
