New description:
I didn't find a way to directly construct fixed sized cpp_int from
existing binary data (a static array, for example an RSA key hardcoded
into a .cpp after being generated with OpenSSL)...
I had to resort to either using the from-string constructor or inserting
the data byte by byte with 8 bit shifts and or-ing in a loop both of which
are ugly and inefficient:

https://svn.boost.org/trac/boost/ticket/9243
...
Ideally it would be possible to create static fixed size numbers as one
creates PODs, without a dynamic initializer being created by the
compiler..
