copysym: Improve compatibility with old compilers.

Some C89 compilers with 32-bit longs won't automatically widen integer
constants to (unsigned) long long in order to represent values that
don't fit in an (unsigned) long, even if those compilers otherwise
support 64-bit long long.

The "ll" and "ull" suffixes seem to get things working.
