Value of M in rsync algorithm

[Hasanat Kazmi]

Hi,

I am a little curious about value of M. Its used in rsync algo for finding
modulus. ( http://samba.anu.edu.au/rsync/tech_report/node3.html ) In rsync,
it is kept to 2^32
What if like Adler 32, M is changed to nearest prime to 2^32, any idea what
effect it will have on resulting check-sums(In terms of collisions)?
