getndelim2 on mingw

[Bruno Haible]

This fixes a compilation error on mingw. I applied it.
getndelim2.c: In function `getndelim2':
getndelim2.c:91: error: `SSIZE_MAX' undeclared (first use in this function)

        * lib/getndelim2.c (SSIZE_MAX): Provide fallback definition. Needed
        for mingw.
