Proposed fixing in the dash: #431320

Maybe somebody interested in making dash use "long int", thus enabling
wider range on 64bit platforms, while still having same on 32bit ones?

Patch for test built-in is ready, now i'm thinking about arithmetics.
Long int is used internally, but then casted to int, that's why
changes are very small indeed.
