Also, checking for <stdio.h> is pointless these days. You can portably assume a C89 compiler (and these days, often a C99 compiler), which guarantees <stdio.h> is present.
Although it's safe to assume C89ish (or even C99ish) these days, there is the possibility that it's a freestanding C implementation, where the C standard does not require <stdio.h>. This might happen in a bootloader, say, where no operating system is available.
