84e42e1daf For cygwin hosts, we need to use the return value from the read 
routine as the number of bytes to process.  This apparently is due to
text-mode vs binary-mode.  If the mounts are done text-mode, then the
size returnedby fstat() may be different than the number of bytes
"read" in text mode.
