 If you calculate 4 * 60175190 bytes = 240700760 which is > 2^31.
 It seems that you have hit the 2GB barrier on 32bit which means that
 either Large File Support (LFS) is not enabled in your copy of winGRASS or
 that r.watershed lacks LFS support on GRASS 6 which I don't believe.

 (maybe related to ticket #1903)
