I was going to prepare a simple pull request that basically added

#if !defined(__RTTI) && !defined(__INTEL_RTTI__) && !defined(__GXX_RTTI) && 
!defined(_CPPRTTI)

#define BOOST_NO_RTTI
#define BOOST_NO_TYPEID

#endif

to intel.hpp, but then I saw that this file doesn't contain any logic for 
BOOST_NO_EXCEPTIONS, relying instead on common_edg.hpp to check 
__EXCEPTIONS.

So I wonder whether the preferred approach wouldn't be to check __RTTI in 
common_edg.hpp instead.

Opinions?

There's also a slight complication here because I suspect that when Intel is 
in Microsoft mode, when RTTI is off it will still support typeid, as MSVC 
does; so just BOOST_NO_RTTI would need to be defined, and not 
BOOST_NO_TYPEID.
