 Ain't that the truth.

 Nope, but if they "officially" support 4.7 and later and still define
 {{{__SIZEOF_INT128__}}} then they'd better support {{{__int128}}} or else
 it's a bug in their compiler support.

 I guess either way we won't do anything about it unless someone complains.
 Hmmm, maybe you're right that a blanket exclusion is safer - at least
 pretty much all of Boost will work just fine then.  OK... I think I've
 convinced myself :-)  I'll commit the original fix unless someone
 disagrees.
