First of all, your problem is that you're using "dirs". Tilde expansion is
done by shell before command is executed, it is not done by xargs, or cygpath.
Replacing "dirs" with "ls" in your command gave me the desired results.

AnrDaemon AT daemon2 ~/cr3
$ ls | xargs -n 1 cygpath -aw
C:\home\Daemon\cr3\bookmarks
C:\home\Daemon\cr3\cache
C:\home\Daemon\cr3\cr3hist.bmk
