There aren't so many (elderly) systems left ... Besides, isn't the  
long long, a data type of at least 64 bits, defined in C, ANSI C99 to  
be exact? Actually, I think, it's sad that no compiler needs to  
follow this option!

Another option is to check whether the size of the variable is bigger  
than four bytes.
