Funny this is: 2.4.6 is exactly the release where many cygwin-related patches landed in rsync code, as I'm seeing from a diff. (I began packaging rsync on CygWin at 2.4.6 and I never had your good idea to test older versions too, what a chanche it is that 2.4.5 is the first working one!)
I attach an purposedly incomplete diff between sources of 2.4.5 and 2.4.6 (I removed 'uninteresting' changes such as configure script changing line numbers...)
[Most notable difference is the addiction of shutdown and the lowering of the sleep time.]
