[Bug c++/36530] ptrdiff_t undefined if is included after and

[faridz at apache dot org]

--- Comment #2 from faridz at apache dot org  2008-06-17 15:03 ---
You're right, the problem in Ubuntu's /usr/include/wctype.h header file:

---
...
/* Get wint_t from .  */
#define __need_wint_t
#include 
...
---

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