Error comes on 4th step:

or some other path for wchar.h (if we're using not default gcc)
wchar.h:131: int swprintf(wchar_t * __restrict, size_t n, const wchar_t * __restrict, ...);
wchar.h:137: int vswprintf(wchar_t * __restrict, size_t n, const wchar_t * __restrict, __va__list);
wchar.h:221: int wcsncasecmp(const wchar_t *, const wchar_t *, size_t n);

All errors comes on size_t...
