In fact, however, that unsigned long long instantiation isn't 
*unconditionally* available, see locale-inst.cc. I think we have to use 
unsigned long as a fall back controlled by the same macro. And please 
add a comment explaining those contortions having to do with the 
available instantiations. Patch pre-approved.

Thanks again,
