Here is a new patch incorporating the test changes suggested by Jonathan 
and removing the stupid paste-o size_t thing.

Regtested and bootstrapped of course.

In addition, for discussion, is a patch with the umsigned long long 
changes.  I made the ctor available ic C++-x *and* have long long.  So 
in we're doing C++-0x and long long is not available you should still 
get the unsigned long ctor.
