 Hi,

 Using c_array() when nullable is in interface, triggers compile error.
 Fallowing code is not compiling.

 {{{
 boost::ptr_vector<boost::nullable<int>> p;
 p.c_array(); //compile error
 }}}

 It looks like inside c_array reinterpret_cast should to {{{value_type*}}}
 not {{{T**}}}.
 {{{
 T** res = reinterpret_cast<T**>( &this->begin().base()[0] );
 }}}
