[boost] LP64 warnings in Boost.Format

Other than a few small issues, the format library is working great for me.

First, in the Boost top-level index.htm:

  <a href="file:///C:/boost/site/libs/format/index.htm">Format Library</a>

Second, there are some issues with LP64 platforms. One one of the
platforms I'm using right now, pointers, longs, and unsigned longs
are 64-bit types. Additionally, size_t, ptrdiff_t, and streamsize
are typedefed to 64-bit types.

Here are the (reformatted) warnings that I'm currently seeing from the
format library. Some of these look like they can be fixed by using
std::streamsize instead of int.
