So we actually had this discussion before to keep it open coded.

If I remember Keith had already sent out patch for this one...

The similiar patch I'd sent went in as 92decf118f1da. I argued symbolic
names helps browsing the code since we can tag/cscope them, so I think
this is a fine change.

I don't understand why our code should include constants and not macros.

And if so, let's do it for all macros we have for the spec. We need one 
policy.
