Hi, I have created https://svn.boost.org/trac/boost/ticket/7479 and 
https://svn.boost.org/trac/boost/ticket/7478 for a similar issue with 
Boost.ratio.

I have committed fixes for this issue 
https://svn.boost.org/trac/boost/changeset/80897 and a partial solution 
for 7478 with https://svn.boost.org/trac/boost/changeset/80896 ( 
Currently there are no macros BOOST_NO_CXX11_U16STRING and 
BOOST_NO_CXX11_U32STRING signaling that the standard library doesn't 
provides std::u16string or std::u32string. The committed change avoids 
the compile error when Boost.Config will provide these macros. In the 
mean time the user needs to define them explicitly while using 
Boost.Ratio in these conditions. )

Please could you check either the trunk or apply the patches associated 
to the tickets?

Best,
Vicente
