7454	Compilation error using gcc 4.1.2 (free not in std namespace)	anonymous	Jürgen Hunold	"'''Error'''
/home/davidsj2/include/boost/units/detail/utility.hpp: In function 'std::string boost::units::detail::demangle(const char*)':
/home/davidsj2/include/boost/units/detail/utility.hpp:48: error: 'mm_free' is not a member of 'std'

On that line, you'll find:
        std::free(realname);

In order to get the software to build, I had to change to:
        free(realname);
