rsync misbehavior on cygwin with network drive

[Nikolay Igotti]

  I noticed that rsync on Cygwin fails to synchronize readonly files, if 
those are on the network drive.

Following simple patch fixes the problem:

                        break;
  #endif

+                                 return -1;
+                         }
+                         do_chmod(from, 0700);
+                         if (do_rename(from, to) < 0) {
+                                 return -1;
+                         }
+                         do_chmod(to, st.st_mode);
+                         return 0;
+                        }

                case EXDEV:
                        if (copy_file(from, to, mode) != 0)
                                return -2;
