Description Farid Zaripov 2008-06-13 16:12:37 UTC
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: ‘ptrdiff_t’ does not name a type
--------------------

Workaround: replace order of included files.

Comment 1 Paolo Carlini 2008-06-14 00:12:36 UTC
If anything, this isn't a libstdc++, because in our implementation of the C++ runtime library <wchar.h> and the other "C" headers are not touched at all.

As a matter of fact, I suspect Ubuntu is at fault, it's know to play strange tricks with the headers. I'll leave to others to analyze that...
Comment 2 Farid Zaripov 2008-06-17 15:03:25 UTC
You're right, the problem in Ubuntu's /usr/include/wctype.h header file:

-----------
...
/* Get wint_t from <wchar.h>.  */
#define __need_wint_t
#include <wchar.h>
...
-----------

Here after that lines should be "#undef __need_wint_t"...
