>             Project: C++ Standard Library
>          Issue Type: Bug
>          Components: External
>         Environment: MSVC, ICC/Windows

> The MSVC declares non-standard prototype of the wcstok():
> wchar.h:
> -----------
> _CRTIMP wchar_t * __cdecl wcstok(wchar_t *, const wchar_t *);
> -----------
> Since configuration script doesn't check the correct prototype and checks only for name, the config.h file contains _RWSTD_NO_WCSTOK macro undefined.
> The MSVC 8 and higher declares wcstok_s() which is identical to standard wcstok():
> wchar.h:
> -----------
> _CRTIMP_ALTERNATIVE __checkReturn wchar_t * __cdecl wcstok_s(__inout_z_opt wchar_t * _Str, __in_z const wchar_t * _Delim, __deref_inout_z_opt wchar_t ** _Context);
> -----------
> I think we need to #define _RWSTD_NO_WCSTOK macro in include/rw/_config_msvcrt.h and add inline wcstok() invoking wcstok_s() in include /ansi/cwchar.
