If a file has DOS (\r\n) line endings and the fd is in binary mode the data
will end with \r when read. If the fd is in text mode the data will not
end with \r, the \r will have been removed and the count of characters read
will be decremented by one.

It's not a bug in Cygwin. I've already posted that I tried your example
with the expected results. I suggest that the contents of your file
contains DOS style line endings and the fd for the read is in binary mode.

Ok, this shouldn't be a problem then.
