Here are the pertinent parts of the relevant '#if" block from ws2tcpip.h:
/*******************************/
#if (_WIN32_WINNT >= 0x0600)

#define InetNtopA inet_ntop
WINSOCK_API_LINKAGE LPCSTR WSAAPI InetNtopA(INT Family, LPCVOID pAddr,
LPSTR pStringBuf, size_t StringBufSize);

#define InetPtonA inet_pton
WINSOCK_API_LINKAGE INT WSAAPI InetPtonA(INT Family, LPCSTR pStringBuf,
PVOID pAddr);

#endif /*(_WIN32_WINNT >= 0x0600)*/
/*******************************/

There's other stuff in that block which I've not shown because it's not
relevant to this particular issue.
As you can see, there will be no issue if _WIN32_WINNT < 0x0600, as is the
case with older mingw-w64 toolchains.
But recent mingw-w64 toolchains define _WIN32_WINNT to 0x0a00.

Cheers,
Rob
