I did not compare library sizes purposefully, but it is very possible to be
the case. If you build the complete version of the library, the resulting
binaries are expected to be large. Someone else asked me a similar question
on the SF, and the answer is, well, because there is lots of code in there.
The setup library is especially big because it contains rather complicated
Boost.Spirit parsers for filters and formatters and it instantiates parsed
filters and formatters for all fundamental types. Multiply that by the
number of character types the library supports.
