3995	array breaks with BOOST_NO_EXCEPTIONS and BOOST_EXCEPTION_DISABLE	peter.myerscough-jackopson@…	Marshall Clow	"I am using boost in the TI Code composer studio environment for an embedded platform which is does not support exceptions. I have therefore had to define BOOST_NO_EXCEPTIONS and BOOST_EXCEPTION_DISABLE to compile with boost::array, BUT I have also had to fix a bug in the use of exceptions. 

On line 171 in array.hpp there is a std::out_of_range exception thrown using the throw statement. This causes an error due to exceptions not being defined.

Further down in the partial specialisation for zero sized arrays, on lines 285-286 another exception is created and thrown using boost::throw_exception. This does not cause an error. The patch therefore is to allow boost::array to be compiled without errors with exceptions disabled. 
{{{
-171                throw std::out_of_range(""array<>: index out of range"");
+171                std::out_of_range e(""array<>: index out of range"");
+172                boost::throw_exception(e);
}}}


It may be more useful to consider putting #ifdef BOOST_NO_EXCEPTIONS around rangecheck(...) to ensure that the function does not get called with BOOST_NO_EXCEPTION, because it will not have any effect. 

Ps. should I have to be defining BOOST_EXCEPTION_DISABLE??
