Adding explicit externs to .c files is not wise as they may
conflict with those contained in system headers.

Does <netdb.h> or other header provide an extern for h_errno?
If not, we'll have to write a macro to detect the lack of an
h_errno extern, define a macro and conditionally provide an
extern (in include/ac/socket.h).

As a matter of fact it does, though it's surrounded by an #ifdef:

   extern int h_errno;

There are several other things that seem to depend on the opposite setting for _XOPEN_SOURCE_EXTENDED, though; for instance:

   #ifdef _REENTRANT
   struct  hostent_data {

And nearly the entire netdb.h file is wrapped by


This is fast getting beyond my knowledge of HP/UX, but I'd be happy to provide copies of man pages and/or .h files if it would help someone else puzzle this out.

Is this why many vendors are reluctant to support threads on HP platforms? It looks like a pain in the butt. When I have a chance, I'll try building this on an HP/UX 11 system and see if it's any different.
