The problem we have run into with long long or (__int64) on at least two 
current compilers is that they provided most (but not 100%) of the 
accompanying functions.  So everything looked OK at first, and then there 
was a missing extractor, or no conversion to double, or whatever.

So it looks like boost should prepare for long long, but not expect it to 
work just yet, even in compilers apparently supporting long long.
