Stephen Nutt started to make the changes, and then got distracted. You
might want to ask him for his current versions.

It seems like most compiler vendors are supporting long long, so my guess
it will eventually become standard. Microsoft was a holdout, but with VC++
7.1 they've added long long. I don't know how extensive that support is;
some vendors long long support is more minimal than others.
