Did you read the section of the Cygwin User Guide that I > cited? If Cygwin uses underlying NT... OS calls for all operations, it should be case-sensitive, but any underlying Win... subsystem calls will be case-insensitive, and YMMV, just as if you used a native Windows command. Maybe stat the file and strace that or the failing ls command above to see what's happening. -- Take care.
