Why is the smallest compiled exe I can do with GCC is 67KB?

Question

I would like to make a very small compiled exe that was written in C. But the smallest I could get is 67KB. I am using MinGW. I tried not to use any header file, and this compiles without errors:

//no header
void main() {
 write(1, "Hello world!", 12);
}

GCC does not show errors if I create and run this, but also 67KB.

I just tried this on x86_64 Linux, which is probably not much different from MinGW at this level, although you never know.

:

#include <unistd.h>

void _start (void) {
  write(1,"Hello world!", 12);
  _exit(0);
}

: gcc -nostartfiles t.c -s -static
