[ squint... ]  Don't know how long that code has been there, but it's
gratuitously unportable.  Even if you grant that "long long" exists
in the compiler, there's no promises whatever as to what width it is.
This code looks to be assuming that it's int64, but just using int64
would be a better answer.

BTW, I now remember that we have an INT64CONST macro in c.h, which
would be another solution if you don't like the cast for some reason.
