<pre>The C standard allows any qualification inside the first array dimension of an
array parameter. The following code is correct C
_Atomic(void (*)(void)) a;
double e(double A[const static 1]){
double *const* a = &A;
return **a;
}
double f(double A[_Atomic static 1]){
double *_Atomic* a = &A;
return **a;
}
but gets a warning from clang 6.0 for f but none for e.
gcc compiles this without any diagnostic as it should.
Thanks
