State-Changed-Why:
    Having given this some consideration, I'm no-longer convinced that
    fixing a lo reigster is a good idea: it would unduly pessimize
    other code and might lead to situations where we would run
    out of registers.
    The best solution would be to make the PIC register a pseudo,
    but apparently there are other issues that prevent this.
    
    I believe the orignal problem that provoked this report has now
    been resolved.
