Forgot one case. On HP-UX 11.00, gethostbyname_r() is properly defined
if -D_REENTRANT is used. Without it, the compiler still accepts the
function prototype but gives a warning about hostent_data going out of
scope. This is because struct hostent_data is not declared. So, we
force an error by trying to set a variable to the struct.
int
gethostbyname_r(const char *, struct hostent *, struct hostent_data *);],[
+struct hostent_data data;
gethostbyname_r(NULL, NULL, NULL);],[
AC_MSG_RESULT(yes)
AC_DEFINE(HAVE_GETHOSTBYNAME_R_3)
int
gethostbyname_r(const char *,struct hostent *, struct hostent_data *);],[
+struct hostent_data data;
gethostbyname_r(NULL, NULL, NULL);],[
AC_MSG_RESULT(yes)
AC_DEFINE(HAVE_GETHOSTBYNAME_R_3)
