Comment(by niels_dekker):

 Fernando (the author of value_init) mailed me that it's okay to him if I
 add an #ifdef to utility/value_init.hpp:

 {{{
   #ifdef BOOST_VALUE_INITIALIZATION_NEEDS_MEMSET
        std::memset(&x, 0, sizeof(x));
   #endif
 }}}

 But therefor, this macro needs to be defined in
 <boost/config/compiler/...>, for the relevant compiler versions. Hereby I
 have attached my proposed additions to the trunk version of
 boost/config/compiler:
 [https://svn.boost.org/trac/boost/attachment/ticket/3869/config_compiler.patch

 config_compiler.patch]  Please check if it's okay.
