I wasn't aware that CPython builds for MSYS2 out of the box, since it's a
POSIX-on-Windows platform like Cygwin. Apparently there are patches that enable
it to build, since MSYS2 has Python available.
For Windows, WCSTOK expands to wcstok_s, which takes a context pointer that
allows concurrently parsing multiple strings in a single thread. The old
function lacks this parameter and instead uses a per-thread static buffer.
They're declared as follows:
wchar_t *wcstok(wchar_t *strToken, const wchar_t *strDelimit);
wchar_t *wcstok_s(wchar_t *str, const wchar_t *delimiters,
wchar_t **context);
Otherwise the WCSTOK macro expands to wcstok, which assumes that POSIX systems
use the standard definition [1]:
wchar_t *wcstok(wchar_t *restrict ws1, const wchar_t *restrict ws2,
wchar_t **restrict ptr);
Apparently the version of wcstok declared in your build environment takes only
two arguments, like the old insecure function in Windows:
wchar_t *__cdecl wcstok(wchar_t * __restrict__ _Str,
const wchar_t * __restrict__ _Delim)
__MINGW_ATTRIB_DEPRECATED_SEC_WARN;
