It's been over five years since the last time I programmed an Alpha in C. Do
you have Ruby running on yours? Are you running DEC/Unix on them? As I
recall, pointers are always a flat 64-bits on Alpha but ints come in several
flavors, so you would have to cast the void* carefully to keep from
narrowing it, but it would fit just fine in a Ruby Bignum.

Are you suggesting to use StringValue and StringValuePtr, and treat the
void* as a char*?
