If <stddef.h> is included after <wchar.h> and <wctype.h>, the following error
occurs:
--------------------
$ cat test.cpp && g++ -c test.cpp
#include <wchar.h>
#include <wctype.h>
#include <stddef.h>
using namespace std;
ptrdiff_t ptr = 0;
test.cpp:9: error: Âptrdiff_t does not name a type
--------------------
Workaround: replace order of included files.
