[j-nsp] force-64bit

Presumably, this is a straight-up recompile.  It is possible that there
was some sloppy coding (most common 32->64 bit conversion problems come
from assuming int and pointer are the same size); that kind of bug
usually gets sorted out pretty rapidly (and would probably be changed in
the common source, not just a 64-bit fork).
