| You reported in another letter that inetutils 1.7 functions properly,

Right.

| Doing a difference check between version 1.7 and 1.8 of the directories
| 'libicmp/' and 'ping/', it strikes me that Gnulib introduces into
| 'Makefile.in' macros related to getaddrinfo() when moving from 1.7 to 1.8.
| Could you experiment somewhat with 'config.h' in the manner of preferring
| gethostbyname() over getaddrinfo()? Improvements?

1.7 have:
#define HAVE_GETADDRINFO 1
#define HAVE_GETDOMAINNAME 1
#define HAVE_GETHOSTNAME 1

1.9.4 have:
#define GNULIB_TEST_GETADDRINFO 1
#define GNULIB_TEST_GETDOMAINNAME 1
#define GNULIB_TEST_GETHOSTNAME 1

#define HAVE_GETDOMAINNAME 1
#define HAVE_GETHOSTBYNAME 1
#define HAVE_GETHOSTNAME 1
#define HAVE_GETSERVBYNAME 1

#define HAVE_DECL_GETADDRINFO 1
#define HAVE_DECL_GETDOMAINNAME 1
