How to get a warning on old exception specifications

Question

I know that among other things (like auto_ptr), exception specifications have been deprecated in C++11.

Is there any way to get a warning from g++ 4.8 with the following code ?

struct F{
    void foo() throw (int){}
};
int main()
{
}

I already tried with -Wall -pedantic -Wextra -Wdeprecated-declarations, but without any success.

You can use

class __attribute__((deprecated)) old_style_throw_specification;
class old_style_throw_specification {};

#define throw(...) throw(old_style_throw_specification, __VA_ARGS__)

Live example

or if you need to support empty throw specifications (thanks @John5342 for pointing this out), you can use

#define throw(...) throw(old_style_throw_specification, ##__VA_ARGS__)

for the macros but you'll need to compile with the GNU-extensions: -std=gnu++11 as the above is not strictly legal C++11.
