I created a share with the same permissions as above on a pre-Vista
machine, just as your share.  The sharing permissions are set to
"Change" for everyone.  I then tried to create a file from another
machine using the same echo command in bash.  I can not reproduce your
problem.  Creating the file worked fine.

So I have no idea why this fails for you.  Maybe it's something with
the share permissions or whatever.  Perhaps an strace shows what fails.
Try

  $ strace -o bash.trace bash -c 'echo foo2 > /cygdrive/z/.cpan/build/foo2'

and send the bash.trace file, then we can have a look.
