Hello,

I've just updated the trunk version of Boost (rev. 71184).
Now GCC 4.6 fails to compile due to the following error:

--- [error] ---
boost-trunk/boost/serialization/version.hpp:57:17: error: conflicting
declaration ‘int boost::serialization::version<T>::value’
boost-trunk/boost/serialization/version.hpp:52:5: error:
‘boost::serialization::version<T>::value’ has a previous declaration
as ‘const int boost::serialization::version<T>::value’
boost-trunk/boost/serialization/version.hpp:57:17: error: declaration
of ‘const int boost::serialization::version<T>::value’ outside of
class is not definition [-fpermissive]
--- [/error] ---

It seems that adding the const specifier fixes the problem, that is:

#ifndef BOOST_NO_INCLASS_MEMBER_INITIALIZATION
template<class T>
const int version<T>::value;
#endif

Could you fix it?

Thank you very much!

Best,
