<pre>void foo(int x) {
if (x && 5) {}
if (5 && x) {}
}
The above produces -Wconstant-logical-operand for the first statement, but not
the second.
This was observed while compiling the Linux kernel, as a single translation
unit has a mix of which side the constant logical operand is on, but only some
of the conditionals producing warnings. In these cases, the constant logical
operand is nested a few macros deep.</pre>
