I just meant that we need to extend the compiler and native codegen to
handle Int64, and follow the appropriate C calling convention.

We can do the change one function at a time using
-D_LARGEFILE64_SOURCE and changing only the functions we want, or we
can use -D_FILE_OFFSET_BITS=64 and change them all at once.
