--- Comment #3 from Bernd Schmidt <bernds at gcc dot gnu.org> ---
For C I'm thinking it should be straightforward to set/check TREE_NO_WARNING (I
have an untested patch).
For the C++ testcase the problem is that the first one is a warning, while the
second one is an error - we can't really omit that.
The C++ errors become even more entertaining when you add -fpermissive:
69972-b.cc:2:16: warning: integer overflow in expression [-Woverflow]
69972-b.cc:2:20: warning: overflow in constant expression [-fpermissive]
69972-b.cc:2:20: note: in template argument for type ‘int’
69972-b.cc: In instantiation of ‘struct S<-2147483648>’:
