Two cents here:

1) There is a potential bug with the checksum if the working tree
is shared (mounted file system for example) between a 32bits host
and a 64bits host. The 32 bits host will write an signed 32bits
checksum while the 64bits host will write a unsigned one.

2) We don't really care so far because nobody use that checksum.
