What's the problem?
 #include <stdio.h>
 #if 0
 C's weird#if 1 /* isn't it */
 #else
 int main(int c, char *v[]) { printf("Hello, world!\n"); return 0; }
 #endif
preprocesses to
 [contents of <stdio.h>]
 int main(int c, char *v[]) { printf("Hello, world!\n"); return 0; }
regardless of whether the preprocessor really tokenizes or not the line
 C's weird#if 1 /* isn't it */
