ChangeSet
  1.2475 05/10/18 19:02:55 aivanov@stripped +1 -0
  Fix for BUG#4375: Windows specific directories are copied
   during replication.
   Modified my_dir(). Now this function skips hidden and system
   files which sometimes are created by Windows.
   NOTE. The fix is similar to the previuos one (05 July 2004)
   except for correct setting of the 'attrib' variable value
   (within the previous fix this variable was left uninitialized
   when my_dir() was called with My_flags & MY_WANT_STAT == 0,
   which gave rise to the bug #4737).

  mysys/my_lib.c
    1.21 05/10/18 19:02:36 aivanov@stripped +13 -2
    Modified my_dir().
     Now this function skips hidden and system files
     which sometimes are created by Windows.

# This is a BitKeeper patch.  What follows are the unified diffs for the
