In Tru64 I got a compilation warning from the src/string.c:

cc: Warning: src/string.c, line 2977: In this statement, the referenced
type of the pointer value "&offs" is "int", which is not compatible with
"unsigned int" because they differ by signed/unsigned attribute.
(ptrmismatch1)
            r = string_unescape_one(char_at, &offs, result->strlen, result);
---------------------------------------------^

The attached patch lazily changes both offs and d to unsigned, which
seems to fine by the Tru64 cc.
