On Cygwin 1.7, if filesystems are mounted with the "noacl" option,
files without write permission (in particular, the temp files created
in write_loose_object()) have their "read-only" flags set in NTFS.
"read-only" files can't be unlinked.
For Cygwin, set write permissions on files that are about to be unlinked.
