In addition, as the test case below shows, the warning is issued inconsistently
between classes and functions, suggesting that the instance of the warning on
the class declaration on line 2 might be a bug rather than a feature:
$ cat -n t.C && g++ -dumpversion && g++ -c t.C
1 struct __attribute__ ((visibility ("default"))) A { };
2 struct __attribute__ ((visibility ("default"))) A;
3
4 void __attribute__ ((visibility ("default"))) foo () { }
5 void __attribute__ ((visibility ("default"))) foo ();
4.3.1
t.C:2: warning: type attributes ignored after type is already defined
