I have the this bit of code in netdb.h
/*
* Error return codes from gethostbyname() and gethostbyaddr() (left in
* extern int h_errno).
*/
#define NETDB_INTERNAL -1 /* see errno */
#define NETDB_SUCCESS 0 /* no problem */
#define HOST_NOT_FOUND 1 /* Authoritative Answer Host not found */
#define TRY_AGAIN 2 /* Non-Authoritive Host not found, or
* SERVERFAIL */
#define NO_RECOVERY 3 /* Non recoverable errors, FORMERR, REFUSED,
* NOTIMP */
#define NO_DATA 4 /* Valid name, no data record of requested
* type */
#define NO_ADDRESS NO_DATA /* no address, look for MX record */
and this in resolv.h
/*
* This used to be defined in res_query.c, now it's in herror.c. It was
* never extern'd by any *.h file before it was placed here. herror.c is
* part of libresolv.a even though it might make more sense in libnetdb.a
* or even libnet.a.
*/
extern int h_errno;

h_errno ought to be declared in <netdb.h> according to the standard.
Can you find it on your machine?
