Description Damien GERARD 2017-02-24 07:39:35 UTC 
Hi,

It seems that `diagnostic ignored -Wcomment` has no effect.
Since nothing states that it does not work, I would expect no warning here.
Thanks :)

```
int main() {
    #pragma GCC diagnostic push
    #pragma GCC diagnostic ignored "-Wcomment"
    /* /* */
    #pragma GCC diagnostic pop
    return 0;
}

gcc -Wall /tmp/foo.cpp
/tmp/foo.cpp:5:5: warning: "/*" within comment [-Wcomment]
```
