Cygwin /usr/bin/getconf CASE_INSENSITIVE /path does not recognise case-sensitive filesystems...

Hi!

----

I got a couple of bugreports that Cygwin $ getconf CASE_INSENSITIVE
/path # does not work and always reports that the filesystem is
case-insensitive - which is not true for NFSv3, and usually not true
for NFSv4.1 filesystems coming from Linux (NFSv4 supports
case-insensitive filesystems, but that is not the issue...)

Example (/cygdrive/l/ is a case-sensitive filesystem):
