cstream.flush() returns EOF before an entire din stream is read for large files
on Windows. The problem seems to be with the DMC library fread/fflush routines.
This is not an issue on Linux.

import std.cstream, std.conv, std.stream;

void main()
{
    int    sum;
    char[] bufr = new char[128];
    char[] line;

    BufferedStream bsi = new BufferedStream(din,4096);
    while(!bsi.eof)
    {
        line = bsi.readLine(bufr);
        if(line.length) sum += toInt(line);
    }

    dout.writefln(sum);
}

(note: the test data is concatenated 8000 times and then redirected into
stdin).
