Hi Corinna,

Rereading the MSDN: Q161338 document I refered to before, Cygwin will need 
to use a minimum 128KB buffer when 'reading' data from tapes - the NT 
specification doesn't allow access to the 'last bytes' in a variable-block 
any other way.  128KB allows for any SCSI device under windows.

(I noticed there was a memcpy for each ReadFile call - so I assume CygWin 
uses its own internal buffers, which may or maynot be large enough for tape
