Done!  :-)

trunk/boost/utility/value_init.hpp:
http://svn.boost.org/trac/boost/changeset/40088
Unit test that would have triggered the warning:
http://svn.boost.org/trac/boost/changeset/40089

Hmmm...  I *expected* to have that warning as well, but I couldn't reproduce 
it!  (At least, not on the trunk version of value_init.hpp.)  So I decided 
to *only* disable the warning mentioned by Gennadiy Rozental, saying that 
"an object of POD type constructed with an initializer of the form () will 
be default-initialized".

Thanks for your feedback!

Kind regards, Niels
