So I wanted to apply this testcase (testcases are great!), but there's a build 
warning:

test_syscall_vdso.c: In function âprint_flagsâ:
test_syscall_vdso.c:239:4: warning: format not a string literal and no format arguments [-Wformat-security]
    printf(bitstr[(r >> bit) & 1]);
    ^

That's with GCC 4.9.2.

Thanks,

	Ingo
