I've added a simple test case to the patch. Note that the patch is not 
trying to replicate the exact behavior of MSVC with respect to exception 
specifications, it only addresses the particular case that causes clang 
to fail on Microsoft's <new>.

In particular, the patch keeps the following code ill-formed:

     void (*q)() throw(int) = 0;
     void (*p)() throw(float) = q;

whereas MSVC accepts it.
