+// such types, however, we have to be careful to use a builtin type
+// whenever possible otherwise we break previously working code:
+// see http://article.gmane.org/gmane.comp.lib.boost.devel/173011
+// for an example and test case.  Thus types like a8 below will
+// be used *only* if the existing implementation can't provide a type
+// with suitable alignment.  This does mean however, that type_with_alignment<>
+// may return a type which cannot be passed through a function call
+// by value (and neither can any type containing such a type like
+// Boost.Optional).  However, this only happens when we have no choice 
+// in the matter because no other "ordinary" type is available.
