I've got to a WinXP machine myself and reproduced the problem with 
plain cygwin rsync. First, it seems to be a bug in cygwin rsync: rsync 
sets strange permissions when instructed not to preserve original 
permissions. The following test illustrates it:

  $ touch a
  $ cp a b
  $ rsync a c
  $ ls -og ?
  -rw-rw-rw- 1 0 Oct 10 16:14 a
  -rw-rw-rw- 1 0 Oct 10 16:14 b
  ----rw---- 1 0 Oct 10 16:14 c

According to man page rsync in such a case should behave the same as other 
file-copy utilities.

As a result "rsync -r" on cygwin just makes downloaded files 
unreadable. I see two solutions -- either make rsync not touch 
permissions at all via "set CYGWIN=nontsec" or make it preserve the 
permissions of the source files. The former works great, the latter 
leads us to the next problem.

Windows seems to want execute permissions for .manifest and .dll 
files. It is probably better to correct this in the repo with a comand 
like this (from a suitable dir):

  find -name '*.manifest' -o -name '*.dll' | xargs chmod +x

Or it could be corrected on the fly (for all files, not only for .manifest 
and .dll) with --chmod option for rsync. Start rsync command with the 
following options:

  rsync -rtp --chmod +x ...

(recursive, preserve modtimes and permissions, assume execute permission 
for all files).
