That's legitimate - my /usr/include/netdb.h has

   #if !defined _LIBC || defined _LIBC_REENTRANT
   /* Use a macro to access always the thread specific `h_errno' variable.  */
   # define h_errno (*__h_errno_location ())
   #endif

The equivalent for errno (instead of h_errno) can be found in 
/usr/include/errnos.h.

If the system header files choose to define h_errno this way, we should use
it and not override it.  (We may have a similar problem with errno, which
would be more important, under some setups).

The configure tests shouldn't #undef h_errno, just check that it is
there and that it can be assigned to (modifiable lvalue).  Similar for
errno, I guess.
