<pre>Test case (prog.c)
int main()
{
struct S;
extern struct S;
}
Compilation command:
clang prog.c -std=c11 -pedantic-errors
Expected output:
An error message since we are using -pedantic-errors and the second
declaration does not declare anything.
Actual output:
No error message.
Note:
gcc correctly reject this program with an error message.</pre>
