Hi,

Today gcc always generates an error when you use a dynamic exception specification with some exception. However I would expect we might also get a warning with -Wdeprecated for "throw()" expressions.

With -std=gnu++17 -Wdeprecated

#include <stdexcept>

void f() throw(); // No deprecation warning saying you should use noexcept instead
void g() throw(std::exception); // Errors in C++17

I would expect a deprecation warning for f.

FYI, clang's -Wdeprecated flag finds and notifies about this.

Cheers,
Romain
