These were small bugs, only relevant for elevation models with NULL cells. The differences should be very small. > Also, do you know if r.watershed in 6.4.RC3 and in a recent Grass 7 version > for Windows(r56229) are consistent? Not for SFD. In GRASS 6.x, surface flow is still creeping along edges (region borders), this has been changed only in GRASS 7. MFD should be identical. r.watershed in GRASS 7 is faster, in particular for the memory mode which reduces memory consumption and keeps intermediate data on disk.
