That has nothing to do with cyglsa-config or installing cyglsa.
FAT/FAT32 does not have the capability to store owner and permission
information on files.  It only supports DOS attributes.  Therefore the
only possible operation on FAT/FAT32 files supported by chmod is setting
or clearing the R/O DOS attribute to fake setting or clearing the 'w'
bit.  chown doesn't work at all.  The owner and group information is
always faked to be the current user.  If you want real permissions and
real user/group information stored on the filesystem, you have to convert
your FAT32 to NTFS.
