--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> ---
An intereting case from PR 103347 where the pedwarn about the NSDMI is
suppressed because GCC thinks the initializer is in a system header:

#include <cstddef>
struct test {
    void *x = NULL; //invalid in C++03 mode
};
int main() {}

This should be rejected with -pedantic-errors, but g++ is silent unless you
also add -Wsystem-headers.
