Well, doesn't that rather depend upon how one indents it?
As I recall, that freedom came with ANSI C.

But yeah, I'd prefer the if(0) type of elimination.

$ cc yes-no.c; ./a.out; cc -DYES yes-no.c; ./a.out; cat yes-no.c
No
Yes
#include <stdio.h>

int main(void)
{
	#ifdef YES
		puts("Yes");
	#else
		puts("No");
	#endif

	return 0;
}
