In C99, executing to the closing brace of main is the equivalent of
return 0.

Even if it's a recursive call to main?

I think so.

C99 5.1.2.2.3 says:

If the return type of the main function is a type compatible with
int, a return from the initial call to the main function is
equivalent to calling the exit function with the value returned by
the main function as its argument; reaching the } that terminates
the main function returns a value of 0.

The way it's phrased, I think the last clause refers to any call to
main, not just the initial call.

It seems to contradict the preceding statement. Anyhow, what if the
code returns a value other than zero, say EXIT_FAILURE?

Execution paths that reach a return statement will not reach the } that
terminates the function.
