To bring in some results from another tool set:

I was test driving the Cairo code on a Analog Devices DSP Blackfin DSP 
the last week, and
the compiler warned me the const type qualifier made no sense on a 
return value.

I also wondered what the const was doing there, but Keith's explanation 
about pure functions
would make sense.

That reminds me of checking the two other warnings I got throughout the
