Yep, that's a bug.

Although I wonder: does it really make sense to include cygwin's path
into PATH?  Isn't cygwin only usefull from within the cygwin prompt?

I tried cygwin some time ago, and was initially broken because I had
installed (native) mingw32 somewhere, so it seemed to me to better keep
cmd.exe and cygwin's paths separate from each other.
