For the following code:

#define MY_MACRO(i)     \
    case i:             \
    {                   \
        break;          \
    }

void f()
{
    int x;
    switch (x)
    {
        MY_MACRO(1)  // WARNING HERE
    }
}

I get a warning at the indicated line: "No break at the end of this case"

However, there is clearly a break there, and hand-substituting the macro expansion makes the warning go away.
