I can't compile the file; the BOOST_NO_STDC_NAMESPACE mistake results 
in a compilation error (which prevents running).  How would I override 
this particular macro?

I could preprocess the file, and here are the results, removing the 
macro printings that result two identical strings (which I think means 
that the macro isn't defined at all):
