[MSVC] MSVC declares non-standard prototype of the wcstok()

                 Key: STDCXX-663
             Project: C++ Standard Library
          Issue Type: Bug
          Components: External
         Environment: MSVC, ICC/Windows
            Reporter: Farid Zaripov
            Assignee: Farid Zaripov
            Priority: Minor
             Fix For: 4.2.1

The MSVC declares non-standard prototype of the wcstok():

_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():

_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.
