The filesystem library in the sandbox is an example of that.

If BOOST_WINDOWS is defined (I'm just doing that on the command line, not
via the Boost config system) the windows.h API is used.

If BOOST_POSIX is defined (again, I'm doing that manually), the direct.h
and similar POSIX headers are used.

Several Win32 compilers supply both windows.h and the POSIX headers, so for
these compilers either flavor works. I'm giving a #error if neither is

Yes, we need to settle on how Boost is going to deal with this API choice.
