Further investigation yielded the same conclusion. Under the C89 standard,
function calls composed of a single identifier that has no declaration act
as if declared as returning an `int`. This is the case for both `main` and
`printf`. See this link: https://stackoverflow.com/a/437763/11672072. I
checked in the actual spec, and the quote is correct.
I suggest verifying your compiler's compliance to spec.
Note: the spec itself gives as an example calling a library function
without declaring it (in §7.1.7, the last example).
