I meant to ask this myself and just forgot.  I changed to this from 
the more normal #define late in the game.  My thinking is that const 
variables are really just symbolic so static initialization should 
still work, but I didn't know where to begin looking in the standard 
to know if this were the case.  If it's not we'll have to go back to 
the #define, which is no big deal, but I should verify this ASAP.
