The obvious issue with C++11 attributes (such as [[noreturn]]) is that the 
syntactic bindings are (or were when I last looked at a draft) 
incompatible with the syntactic bindings for GNU __attribute__, so meaning 
that C++11 attribute support in GCC will need to deal with different 
syntactic forms of attributes in the same place binding differently.
