+// Purpose:       This file provides the standard defines required by ISO C
+// Description:   This file is really provided by the compiler, although in
+//                due course we may override things here.
+//
+//                The main purpose of this file is as a comment to the FAQ
+//                about where stddef.h lives: it is provided by the compiler,
+//                which for current gcc can be found by looking in the
+//                include directory in the same place as the specs file
+//                which you can determine from TARGET-gcc -v,
+//                e.g. arm-elf-gcc -v
+// Usage:         #include <stddef.h>
