Unfortunately, Internet Explorer has a habit of creating filenames that push
the limits of what the filesystem can handle. The problem you are running
into is not a bug in rm, but a limitation of cygwin1.dll. Dave's suggestion of
shortening the overall pathname by moving the containing directory is the
best approach I know of. However be aware that the current cygwin
filename limitations are on the translated Windows version of the name,
so depending on where / is mounted it consumes more or less of the
filename buffer limit, not necessarily the length on the command line.

Again, because it is not a bug in rsync, but a fundamental limitation in
cygwin/Windows. You can also google this list to learn about attempts
to increase the filename length limitation in cygwin for NTFS by using
the alternate Windows API that has a more generous length limit (32k
instead of 256), but no one has yet contributed a complete patch that
does that job without breaking cygwin on Win9x or adding too much
overhead.

You know, upgrading may help as well, as there was a patch in
cygwin-1.5.15 to increase PATH_MAX by one, which MIGHT have been
enough for your example (but no guarantees). Currently, cygwin is at
1.5.18, bash at 3.0-8, and coreutils-5.3.0-9 replaces fileutils-4.1-2.
