shell expansion produces e.g. "ls: cannot access '*.pdf': No such file or directory" in Windows CMD shell, but works okay in bash

[Paul Moore]

Is this because cygwin globbing is (by default) case sensitive? You
could set the CYGWIN environment variable to "glob:ignorecase" to get
case-insensitive behaviour.
