On recent version of FreeBSD (5.3 and later, which are required to run 
Wine), /usr/include/netdb.h has the following snippet:

  #if 0
  /* obsoleted */
  #define EAI_NODATA       7      /* no address associated with hostname */
  #endif

I did some archeology, and for earlier versions of FreeBSD the definition 
in netdb.h indeed was used, and in fact the reference to EAI_NODATA under
/usr/include.

One would indeed expect that, but according to my tests it's not needed.
