This was already stated.

You could try testing the following things:

$(cygpath d:/) # don't capture the output but execute cygpath in a subshell
sh -c "cygpath d:/" # force the subshell to be "sh"
$(cat /dev/null | cygpath d:/) # see if pipes work the same as input redirect
$(cygpath d:/ > /tmp/cygpath.out) # see if redirecting output also affects it

I'll let you know if I think of other things to try.
