Given the function:
BOOL
invalid_crc(char * pcnd, int length)
{
    return(calculate_crc(pcnd, length) != 0));
}
where calculate_crc() is a function which returns an int and BOOL is
defined as a system "16-bit Boolean value" (no definition given of
"Boolean" that I could find).  Would it be proper in this instance to
drop the " != 0"?  Can boolean have all the values of an int (with
only 0 and everything else counting)?
