    /* We trust previous int21 call more if free hasn't maxed out. */
    if( free < blocks )
    {
        /* Previous bsize is a multiple of this bsize, so the multiplication
        and division here is really a rescaling of the previous free
        value. */
        free *= bsize;
        bsize = _farpeekw (_dos_ds, __tb + 0x2 + 0x2) *
            ( _farpeekb (_dos_ds, __tb + 0x2 + 0x4) + 1 );
        free /= bsize;
    }
    else
    {

            65536 * _farpeekw (_dos_ds, __tb + 0x2 + 0x21);

Thanks, I'm sending a diff to DJ right now, just let me change the layout of
the sources back to its original form (tabs, spaces, indent, etc.)
