What generic LP64 documentation do you have? I could certainly believe
some architecture ABI says "LP64 => size_t == unsigned long" here, or
some platform, but I don't think ARM does. And I don't think anyone
else really has the authority, unless using "long long" is
fundamentally broken somehow.

Cheers.
