c:/foo and c:/foo/bar are perfectly acceptable windows paths.  Some
windows utilities don't accept this style of window path on the command
line but they are recognized by all of the windows functions which use
paths.

I don't know python but I am not surprised that a cygwin version of
python would be "confused" by the use of colons in path names since
avoidance of that kind of path is one of the main reasons for cygwin's
existence.  The cygwin DLL does try to handle dos paths correctly but
that doesn't mean that a UNIX program which manipulates UNIX path names
will be happy to see them.
