11545	Sentry problem	lcarreon@…	Andrey Semashev	"I compiled Boost 1.59.0 with Solaris Studio 12.4 in C++11 mode and I
get the following error messages:

""./boost/log/utility/formatting_ostream.hpp"", line 627: Error: Cannot use boost::log::v2_mt_posix::basic_formatting_ostream<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t>>::sentry to initialize bool.

It seems that the problem here is that the conversion operator of the
sentry base class is not exposed by the derived class.  The fix I
found suggested defining the required conversion operator on the
derived class.  Add the following line in boost/log/utility/formatting_ostream.hpp:

  operator bool() { return base_type::operator bool(); }

after the lines:

  BOOST_DELETED_FUNCTION(sentry(sentry const&))

  BOOST_DELETED_FUNCTION(sentry& operator= (sentry const&))
