m4/getaddrinfo.m4 tests for getaddrinfo with:
AC_CHECK_FUNCS(getaddrinfo
This assumes getaddrinfo is available on the system under the name
`getaddrinfo'. Not so on Tru64 UNIX 5.1 where <netdb.h> has:
#if defined (_SOCKADDR_LEN) || defined (_XOPEN_SOURCE_EXTENDED)
#define getaddrinfo ngetaddrinfo
#else
#define getaddrinfo ogetaddrinfo
#endif
The correct method to test for getaddrinfo on this system is to
include <netdb.h> and try linking a program using getaddrinfo(). Patch
attached.
