HEAD build troubles, buildfarm misconfigurations

Trying to build 8.3 from the stable snapshot again (yes, I'm a glutten for
punishment), and using the following config options:

./configure --prefix=/home/rob/devel/postgresql/83snapshot20070904/pgsql/
--enable-cassert --with-perl --enable-debug --with-pgport=5483 --with-libxml

I get the following error during make (configure runs fine)

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -g -DFRONTEND -I. -I../../../src/interfaces/libpq -I../../../src/bin/pg_dump -I../../../src/include -D_GNU_SOURCE -I/usr/include/libxml2 -c -o

Looking at /usr/include/netdb.h I see in that section

# ifdef __USE_GNU
/* Structure used as control block for asynchronous lookup. */
struct gaicb
{
const char *ar_name; /* Name to look up. */
const char *ar_service; /* Service name. */
const struct addrinfo *ar_request; /* Additional request specification. */
struct addrinfo *ar_result; /* Pointer to result. */
/* The following are internal elements. */
int __return;
int __unused[5];
};

/* Lookup mode. */
# define GAI_WAIT 0
# define GAI_NOWAIT 1
# endif

If anyone has any ideas on what might fix the above, I'd be interested in
hearing them. (And oddly, the snapshot built fine a couple days ago)

The second half of this story is that I thought it was odd none of the
buildfarm machines had reported this error, so I went poking for another
ubuntu machine (I am running Ubuntu 6.06), preferrably one that was also
trying to build xml, and I noticed "barasingha" (ubuntu 7.04) was configured
with --with-xml, which afaict should produce nothing more than a configure
warning. I looked at a handful of other machines configured for xml and they
all seemed right, but maybe someone can do a more thorough search in the db?
Or maybe there is a way to capture configure warnings?
