You could not; enabling large file support on Windows required structural
changes to the Python implementation.  The limitations before 2.2 were
inherited from that Microsoft's implementations of "regular old portable C
library functions", like stat(), were restricted to 32-bit results.  So
getting sensible results for large files on Windows required calling a
variety of Windows-specific functions under the covers.
