just because it's a 64bit system doesn't automatically mean 64bit
integers, especially when it comes to databases and other data storage
formats.  it's also possible to use 64bit ints on 32bit systems with a
performance penalty, so hopefully it's just a matter of increasing the
size of an internal file pointer variable (likely in multiple places)
and recompiling.
