The retry pattern is duplicated in three places. It also seems to be too hard to use: mingw_unlink() and mingw_rmdir() duplicate the code to retry, and both of them do so incompletely. They also do not restore errno if the user answers 'no'. Introduce a retry_ask_yes_no() helper function that handles retry with small delay, asking the user, and restoring errno. mingw_unlink: include _wchmod in the retry loop (which may fail if the file is locked exclusively). mingw_rmdir: include special error handling in the retry loop.
