Let's be thorough and try all the combinations :)

void Tester() {
__complex short a1;
__complex int a2;
__complex float a3;
__complex double a4;
short a5;
int a6;
float a7;
double a8;
#define TestPair(m,n) int x##m##n = a##m+a##n;
#define TestPairs(m) TestPair(m,1) TestPair(m,2) \
                     TestPair(m,3) TestPair(m,4) \
                     TestPair(m,5) TestPair(m,6) \
                     TestPair(m,7) TestPair(m,8)
TestPairs(1); TestPairs(2);
TestPairs(3); TestPairs(4);
TestPairs(5); TestPairs(6);
TestPairs(7); TestPairs(8);
}

(At the very least, you missed the float + complex integer case.)
