8725	GCC 4.8 warns of ignored attribute in declaration	Chris Stylianou <chris5287@…>	Vladimir Prus	"When compiling with -Wall (GCC 4.8.0) the following warning is raised as an error:

{{{
In file included from libs/program_options/src/variables_map.cpp:12:0:
./boost/program_options/variables_map.hpp:30:11: error: attribute ignored in declaration of ‘class boost::program_options::variables_map’ [-Werror=attributes]
     class variables_map;
           ^
./boost/program_options/variables_map.hpp:30:11: note: attribute for ‘class boost::program_options::variables_map’ must follow the ‘class’ keyword
}}}

This is caused by friend class declaration below having the attributes in the wrong order. Below is the simple fix.
