/* Vector Crays doesn't have a good 32-bit type, or more precisely,

int32_t as defined by <bind/bitypes.h> isn't 32 bits, and we don't

want to depend in being able to redefine this type. To cope with
|

this we have to clamp the result in some places to [0,2^32); no

need to do this on other machines. Did I say this was a mess?
