--- 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.

And this is a regression, because 4.8 silently accepts this code in C++98 mode,
whereas 4.7 warns about it as expected:
null.C:3:15: warning: non-static data member initializers only available with
-std=c++11 or -std=gnu++11 [enabled by default]

Note the original issue with -Wzero-as-null-pointer-constant is fixed in GCC 9
by r9-873. The system header issue is now listed as PR 77299.
