7898,TI compiller: wrong decision about type_info presence in boost/config,Girman Ilya <ilya.girman@…>,John Maddock,"Hello!

When I try to include boost/static_assert.hpp on Texas Instruments compiler (TMS320C6x C/C++ Compiler v7.3.8) I get an error ""... ../cots/boost/boost/config/suffix.hpp"", line 574: error !#284: the global scope has no ""type_info""

There is a fault place:

{{{
// When BOOST_NO_STD_TYPEINFO is defined, we can just import
// the global definition into std namespace:
#if defined(BOOST_NO_STD_TYPEINFO) && defined(__cplusplus)
#include <typeinfo>
namespace std{ using ::type_info; }
#endif

}}}

Source of issue is that boost incorrectly determines presence of type_info in std namespace:

boost/config/stdlib/dinkumware.hpp:
{{{
#include <typeinfo>
#if ( (!_HAS_EXCEPTIONS && !defined(__ghs__)) || (!_HAS_NAMESPACE && defined(__ghs__)) )
#  define BOOST_NO_STD_TYPEINFO
#endif
}}}

At this moment my workaround is to add !defined(!__TI_COMPILER_VERSION!__) to condition above.

Previously I used boost 1.37 which has no ""BOOST_NO_STD_TYPEINFO"" section in dinkumware.hpp file.

TI has some specific config for boost (http://processors.wiki.ti.com/index.php/Building_and_Running_Boost_Code_with_the_C6000_Compiler). This issue takes place with these patches also.
