Hrm, that commit is actually in -next and Paul's pull request, not sure why it wasn't showing up in greps. The issue is that you've added a dependency from nolibc's stdio.h to unistd.h but nolibc.h includes unistd.h last and there's no other include, meaning that at the time that stdio.h is compiled there's no definition of the constants visible. The below fixes the issue, I'll submit it properly later today: diff --git a/tools/include/nolibc/nolibc.h b/tools/include/nolibc/nolibc.h index 04739a6293c4..05a228a6ee78 100644 --- a/tools/include/nolibc/nolibc.h +++ b/tools/include/nolibc/nolibc.h @@ -99,11 +99,11 @@ #include "sys.h" #include "ctype.h" #include "signal.h" +#include "unistd.h" #include "stdio.h" #include "stdlib.h" #include "string.h" #include "time.h" -#include "unistd.h" #include "stackprotector.h" /* Used by programs to avoid std includes */
