[boost] [lexical_cast] exception type for overflow

Hi!

i would expect that
lexical_cast<uint16_t>("65536")
and
numeric_cast<uint16_t>(lexical_cast<int>("65536"))
would throw the same exception boost::numeric::positive_overflow.
but lexical_cast throws a bad_lexical_cast.

is it possible to change lexical_cast so that it also throws 
positive_overflow
if the error comes from the overflow and not from the lexical parsing?
