This version uses BOOST_WORKAROUND. Please, have a look.
Tested on sun c++ 5.9 and gcc4.3.3.
The same modifications of libs/mpl/test/string.cpp.

The patch adds #include <boost/mpl/empty.hpp> and #include
<boost/mpl/if.hpp> to boost/mpl/string.hpp on all platforms. This can
also be made only for sun. Do you think it's needed?

BR, Dmitry
