  If you build from mainline source, (i.e. the upcoming 1.7 cygwin) you'll already get:

2007-01-04  Brian Ford  <>
	    Corinna Vinschen  <>

	* fhandler.h (PREFERRED_IO_BLKSIZE): Define as 64K.
	* fhandler.cc (fhandler_base::fstat): Set st_blksize to
	PREFERRED_IO_BLKSIZE.
	* fhandler_disk_file.cc (fhandler_base::fstat_helper): Ditto.
	* fhandler_mailslot.cc (fhandler_mailslot::fstat): Ditto.
	* fhandler_raw.cc (fhandler_dev_raw::fstat): Ditto.

  If you want to stick to 1.5 series, you could download a snapshot (source) and merge the diffs in yourself easily enough.


    cheers,
      DaveK
