I set up Cygwin on Vista today and did some testing:

2017-02-13 22:28:37 admin at vista ~
$ ls -l /cygdrive/d
total 4355764
-r--r--r-- 1 admin None 4460298272 Feb  9 08:52 201701_TAR.CPT

File size is correct, file mtime is correct, contents can be read 
correctly, but file names are mangled (I missed that before?).


So, do I file a bug report?  /usr/src/sys/fs/cd9660?
