Yes, the compiler should use a larger type than int for the enum.

Can it be persuaded to do so? Maybe it ignores the cast to size_type
and uses an int because -1 will fit in an int, in which case maybe
this would make it use a bigger type:

    enum npos_type { npos = -1UL }

Just a thought. I've never used vacpp let alone tested this code with it,
