            Bug ID: 24376
           Summary: -Wall flag position should not matter
           Product: clang
           Version: 3.6
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: j2jey at hotmail.com

    Classification: Unclassified

Here is a small example

int main(){ 
    int a; 
    return 0; 
}

I compile it with
clang++ -Wall -W -Werror -Wno-error=unused-variable main.cpp

And I have the expected warning.
Now If I compile with:
clang++ -W -Werror -Wno-error=unused-variable -Wall main.cpp

It triggers an error, so it seems like the position of Wall changes the
behavior, which I think is not expected.
