This explanation would be clearer if you used the option -lineno (or -all) when
dumping.

Ideally, the warning should be given in "return f". Perhaps there is a way to
adjust the locations?

I guess that for:

     4  typedef _Complex float C;
     5  C foo()
     6  {
     7    C f;
     8    __imag__ f = 0;       /* { dg-warning "is used" "unconditional" } */
          __real__ f = 0;
     9    return f;
    10  }

there is no warning, no?
