[avagin at localhost ~]$ cat test2.c
#define _GNU_SOURCE
#include "stdio.h"

#define PTRACE_PEEKSIGINFO_FLAGS_MASK (~0UL << 16)

int
main(int argc, char *argv[])
{
	printf("%lx\n", PTRACE_PEEKSIGINFO_FLAGS_MASK);
	return 0;
}
[avagin at localhost ~]$ gcc -Wall -iquote . test2.c

I want to get an error in this case, because stdio.h isn't in a current
diretory.
