I don't really have much free time at the moment. However I will try
to give it a shot. What is the right place to take latest source code 
from? Regular Boost CVS repository on SourceForge?

Right, this will do it. I think I shall pursue this way.
However, date is quite a low-level class, and it sounds perfectly 
reasonable to create a vector of dates.
My opinion is that ability to create vectors is a strong argument for 
providing default constructor; it is not really that important what
exact value it sets date to, as long as it is not a regular date. I 
personally have a slight preference for not_a_date.

After all if default value is a real issue we can always parameterize
date with "DefaultValuePolicy" giving users way to control it. I 
doubt though that many people will change it.
