It would also help to know what compiler is used. On MSVC, we use response files,
so the size of the command line is not important. gcc on linux enjoy a generous
limit on the command line length. gcc on windows might be problem -- if you check
that your version does support response files, I probably can modify boost.build
to take advantage of that.
