Grep doesn't tell the whole story.  Look at the previous ten lines:

#if !defined(_XPG4_2) || defined(__EXTENSIONS__)
#define NO_ADDRESS      NO_DATA         /* no address, look for MX record */

/* BIND */
#define NETDB_INTERNAL  -1      /* see errno */
#define NETDB_SUCCESS   0       /* no problem */
/* End BIND */

#define MAXHOSTNAMELEN  256

Maybe gcc doesn't define __EXTENSIONS__.   You could try setting
CXXFLAGS="-g -O2 -D__EXTENSIONS__" when running gcc's configure;
not sure if that's how to jam that define in there, but it sounds
good to me.

BTW a very OT thanks to Sandia for fabricating the rad-hard NS32C016
CPUs used in the Mars Observer Camera.  Ran at all of 10MHz, but that's
all we needed... http://ida.wr.usgs.gov/corrections/mocinst.cat
