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 -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
