This is not an unpopular opinion per se, but one that puts you firmly in the "semi-portable C" camp (in the "camp" model of the essay I linked in another comment), while the compiler vendors themselves have moved entirely away from that camp into the "standard C" camp. As I wrote, "The principles and practices in one camp can seem alien, even threatening to another."
