It looks that on cygwin, file-name-case-insensitive-p returns different
values for existing and non-existing files:

--8<---------------cut here---------------start------------->8---
M-! touch /tmp/foo

(file-name-case-insensitive-p "/tmp/foo")
=> nil

(file-name-case-insensitive-p "/tmp/bar")
=> t
--8<---------------cut here---------------end--------------->8---

The doc of file-name-case-insensitive-p does not require that FILENAME exists.
