title: How do you build the x64 Boost libraries on Windows?
body: <p>I've built the x86 Boost libraries many times, but I can't seem to build x64 libraries. I start the "Visual Studio 2005 x64 Cross Tools Command Prompt" and run my usual build:</p>
  
  <pre><code>bjam --toolset=msvc --build-type=complete --build-dir=c:\build install
  </code></pre>
  
  <p>But it still produces x86 .lib files (I verified this with dumpbin /headers).
  What am I doing wrong?</p>
