Run the attached file with -Wconversion
When compiling the attached file, a conversion warning is given if the compiler
is GCC. This does not happen with CLANG.
$ g++ -Wconversion example.cpp
example.cpp: In instantiation of ‘void print_byte_order(T) [with T = short
int]’:
example.cpp:12:27: required from here
example.cpp:7:5: warning: conversion to ‘short int’ from ‘int’ may alter its
