Subject: [Boost-testing] [date_time] gcc 3.4.6 - int_adapter<T>::from_special(special_values) is not inlined, so duplicated (#6302)

Hi,

I know that gcc 3.4.6 is an old compiler version, but there are a lot of
error on the Boost.Thread regression tests. I have created a ticket
#6302 <https://svn.boost.org/trac/boost/ticket/6302>
int_adapter<T>::from_special(special_values) is not inlined, so
duplicated. <https://svn.boost.org/trac/boost/ticket/6302> to follow
this issue

It seems that this function

template<typename int_type_>
class int_adapter {

   static int_adapter from_special(special_values sv)
   {
     switch (sv) {
     case not_a_date_time: return not_a_number();
     case neg_infin: return neg_infinity();
     case pos_infin: return pos_infinity();
     case max_date_time: return (max)();
     case min_date_time: return (min)();
     default: return not_a_number();
     }
   }

is not been inlined with gcc 3.4.6 and so it is duplicated at link time.
See link error on regression test

Is this a know error for this compiler version?
