No, in fact I don't think any of the examples are default constructable.

There should be no requirements ont the constructor. date_names_put is the
base interface while all_date_names_put is an implementation that allows the
passing of a bunch of char arrays to get the desired date output.

I'm not sure where you are seeing these examples, but if you looking in
libs/date_time/test/gregroian/testfacet.cpp I don't think you will find any
default constructors.

Maybe you can send me some of the errors you are getting -- onlist or off --
your choice?
