getaddrinfo is a macro in <netdb.h>: #if defined (_SOCKADDR_LEN) || defined (_XOPEN_SOURCE_EXTENDED) #define
getaddrinfongetaddrinfo #else #define getaddrinfo ogetaddrinfo #endif
 

The solution is to either revert to the 8.1.1 code (my recommendation)
or check for ngetaddrinfo. The latter is a crude hack though.

$ nm /usr/shlib/libc.so | grep getaddrinfo 
__ngetaddrinfo                   | 0004395900636352 | T | 0000000000000008
__ogetaddrinfo                   | 0004395900637184 | T | 0000000000000008
ngetaddrinfo                     | 0004395900636352 | T | 0000000000000008
ogetaddrinfo                     | 0004395900637184 | T | 0000000000000008
