GCC is supposed to suppress division by zero warnings when floating point. 
However the warning is based on the lexical form, i.e. the unpromoted type.  I
suggest it should depend on the promoted type.

float f[] = {
 1.0f/0.0f,  // No warning
 1.0f/0      // Warning (and diagnostic is on the wrong line in 3.3 at least)
};
