  Do they have numbered defines allowing _SCO_DS >= 50005 or some such ?

  hum, as you understadn I would actually prefer to avoid starting 
to go that game, especially if one need more defines for HPUX as 
in the bug I pointed to.

  that part is optional, it *just* improve the error message returned
in case of failure ... what I tried to attain was to not compile that
section if one can identify that there is no support for it. I would
have expected that having HAVE_NETDB_H and HOST_NOT_FOUND which is one
of the values taken by h_errno would be sufficient to have that 
extern defined. 
  I'm honnestly tempted to now scrap this part except on the couple of
platform where I know the compilation will work.
