Where would I be expected to find some indication whether they have made
their changes proprietary ? Is it required to be in each source file, or
is it required to be in some other place related to the Boost
distribution they supply, and if so where ?

I have been in contact with one of their representatives, so I will ask
him point blank about it, but I did want to know in advance if there was
any requirement they specify their copyright changes in some particular
place related to their distribution of the source code.
