<pre>GCC supports -Wbool-compare compiler flag as seen from
<a href="https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html">https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html</a>
For portability, it would be nice if Clang also supported -Wbool-compare flag.
Sample code at <a href="https://wandbox.org/permlink/WO2fLz8XtrLpXhu6">https://wandbox.org/permlink/WO2fLz8XtrLpXhu6</a> shows GCC warning
with -Wbool-compare and Clang warns with
-Wtautological-constant-out-of-range-compare.</pre>
