Not quite sure about the validity of this code (we take the address 
of a temporary -- I guess it should be valid, but undefined), but 
this nasty error message that is ten times as long as the code in  
question is not appropriate: 
--------------------- 
typedef int I2[2]; 
int main () { 
  int *p = (I2) {1,2}; 
} 
---------------------
