cp and mv behave differently when trying to overwrite an in-use executable:

cp: cannot create regular file `/bin/mintty.exe': Device or resource busy
$ mv mintty.exe /bin
[works fine]
That's on 1.7. On 1.5, both cp and mv fail.
Same when trying to 'rm' an in-use executable: Works on 1.7, fails with
'Permission denied' on 1.5. Cygwin 1.7 works like Linux here. I don't
know whether POSIX requires this behavior.
The difference probably occurs because 1.7 now uses
NtSetInformationFile() instead of MoveFileEx() and DeleteFile().
