+ * getaddrinfo.h
+ *	  Support getaddrinfo() on platforms that don't have it.
+ *
+ * Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO,
+ * whether or not the library routine getaddrinfo() can be found.  This
+ * policy is needed because on some platforms a manually installed libbind.a
+ * may provide getaddrinfo(), yet the system headers may not provide the
+ * struct definitions needed to call it.  To avoid conflict with the libbind
+ * definition in such cases, we rename our routines to pg_xxx() via macros.
+ *
+
+in lib/replace we use rep_xxx()
+
+ * This code will also work on platforms where struct addrinfo is defined
+ * in the system headers but no getaddrinfo() can be located.
