In Unix, applications generally don't parse paths, the shell does.
The shell then passes the expanded paths to the applications.

In most if not all Unix shells including bash, a backslash quotes or
removes special meaning from the following character.  If you type
PATH\* as a command argument at the bash prompt, the shell will see
that as PATH followed by a literal * and will pass the string PATH*
to the application.

Cygwin is intended to provide a Linux-like environment.  Linux
doesn't use backslashes as path separators, so you shouldn't expect
a backslash-separated path to work under Cygwin.  If you need to
pass a Windows path to a Cygwin program, use cygpath.

Gary
