I noticed that rsync on Cygwin fails to synchronize readonly files, if
those are on the network drive.
Following simple patch fixes the problem:
*** rsync-2.6.6/util.c Thu Jul 7 23:49:14 2005
--- util.c Fri Mar 10 02:46:31 2006
***************
*** 380,385 ****
--- 380,402 ----
return -1;
break;
#endif
+ /* Cygwin somewhat misbehaves with R/O files on
network drive

+ STRUCT_STAT st;

+ do_chmod(to, st.st_mode);

case EXDEV:
if (copy_file(from, to, mode) != 0)
