No, it's really static: it can perfectly see what both possible formats are, so 
it may, indeed, warn that in one of the cases the arguments are not used.  I 
would bet that this warning would be addressed if GCC made similar warnings.  
But in the current state of affairs, I don't feel like lobbying to get patches 
applied in this piece of code.
