Rob,
Next is quoted from mingw ws2tcpip.h:
..........
#if (_WIN32_WINNT >= 0x0501)
void WSAAPI freeaddrinfo (struct addrinfo*);
int WSAAPI getaddrinfo (const char*,const char*,const struct addrinfo*,
                        struct addrinfo**);
int WSAAPI getnameinfo(const struct sockaddr*,socklen_t,char*,DWORD,
                       char*,DWORD,int);
#else
/* FIXME: Need WS protocol-independent API helpers.  */
#endif
..........

But since it is a stdcall function configure cannot detect it and the 
in mingw case code will use gethostbyname even we configure with 
CPPFLAGS="-DWINVER=0x0501" (this set _WIN32_WINNT to specified WINVER).


Michael, please could you check preprocessor output.
May be in you case GetAddrInfo is defined by <ws2tcpip.h>.
