$ uname -a
CYGWIN_NT-10.0 xxxxxx 2.6.0(0.304/5/3) 2016-08-31 14:32 x86_64 Cygwin

$ mkdir A

$ mkdir a
mkdir: cannot create directory ‘a’: File exists

$ rmdir A

$ touch A && ls -l A
-rw-r--r-- 1 cygSimple cygSimple 0 Nov 18 10:26 A

$ sleep 60 && touch a && ls -l A
-rw-r--r-- 1 cygSimple cygSimple 0 Nov 18 10:27 A


My installation is on the native C:\ drive that is NTFS.
