On windows b2 --help prints wrong text.

[nanoric]

On Windows, b2 --help says:

  --prefix=<PREFIX>       Install architecture independent files here.
                          Default: C:\Boost on Windows
                          Default: /usr/local on Unix, Linux, etc.

But if the user calls b2 install, only C:\Boost\include will be installed. The libraries will not be installed into C:\Boost\lib.

Only by calling b2 --prefix=C:\Boost install will both headers and libraries be installed correctly.
