            Bug ID: 17773
           Summary: Failure compiling Boost type_traits with Boost build
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows XP
            Status: NEW
          Severity: normal
          Priority: P

If I compile Boost type_traits with the latest clang for Windows using the VC++
RTL and headers I receive the error message:

--------------------------------------------------------------------------------

If I add '-D_HAS_EXCEPTIONS=0 /GR-' as recommended I then get, when including
'typeinfo':

--------------------------------------------------------------------------------

        : public exception" 

--------------------------------------------------------------------------------

In effect trying to turn off RTTI and exceptions gives me an error just trying
to include typeinfo. So clang needs to be able to compile using VC++ RTL with
typeinfo support and exception support else it is unusable in Boost.
