hello world in C without semicolons and without IF/WHILE/FOR statements [closed]

#include <stdio.h>

int main() {
    switch (printf("Hello, world!\n")) {}
}

If your friend says "oh, you can't use switch either," then:

#include <stdio.h>

int main(int argc, char *argv[printf("Hello, world!\n")]) {}

I've been trying to find a "portable" way of stealing a semicolon from an include file. This works under Linux:

int main(int ac, char **av)
{
#define typedef
#define uint8_t a[printf("hello world\n")]
#include <stdint.h>
}

This causes the one typedef unsigned char uint8_t to become my printf.

Another trick that worked was to #define away every standard stdint type such that stdint.h reduces to a bunch of semicolons.

Both of these fall flat on FreeBSD because it uses private intermediate types (like __uint8_t) which means that removing typedef fails in the quoted example and prevents me from successfully removing all non-semicolons in the other case.

It seems like it should be possible to steal a semicolon cleanly from an include file. Can anyone improve on my attempt?
