bug 1110812 - 4Gigbug.patch does not work in Windows

Hi,
This is regarding the 4Gigbug.patch for the bug request id: 1110812. 
This patch works well in Linux for file sizes more than 4GB. But the 
large file problem (greater than 4GB) still exists in Windows. I think 
here is what is happening.

The fseek  in rs_file_copy_cb() method of buf.c still throws an error 
when the seek is beyond 4GB. We tried changing the fseek to _lseeki64 
and typedefinition of rs_long_t to __int64. But the problem is still 
there. We do not know how to get fseek to work for large files (>4GB) in 
Windows.

The error thrown in librsync while applying the delta is :

librsync: ERROR: (librsync) seek failed: Invalid argument
librsync: ERROR: (librsync) patch job failed: IO error

Can someone help with this.

Thanks
Sekar.
