Compiling src/process.c with -E -dD I get in the output:

	#define HAVE_GETADDRINFO 1
	...
	#define HAVE_RES_INIT 1
	...
	#define res_init res_9_init	/* from resolv.h */
	...
	int res_9_init (void);		/* from resolv.h */
	...
	      res_9_init ();	/* line #3094 src/process.c in  
"make_network_process" */
			/* could also happen on line #3144 when HAVE_GETADDRINFO is 0 */

Nm tells about libc:

	/usr/lib/libc.dylib(res_init.o):
	9004561c T _res_init

so it's obviously a mistake to re-define res_init as res_9_init. This  
re-definition happens in resolv.h in:

	#ifndef __BIND_NOSTATIC
	...
	#define res_init			res_9_init
	...
	__BEGIN_DECLS
	...
	int		res_init __P((void));
	...
	__END_DECLS
	#endif

In the Fink project for compilation of netcat 0.6.1 CFLAGS is set to

	-D__BIND_NOSTATIC

Re-configuring with this among the CPPFLAGS used allows to create  
temacs. /usr/include/resolv.h is the only file that uses  
__BIND_NOSTATIC, src/process.c is the only file that includes  
resolv.h (found by compiling with -H), so on (some ?) Mac OS X src/ 
process.c should be compiled with an extra CPPFLAG or CFLAG - 
D__BIND_NOSTATIC when HAVE_RES_INIT is 1.

Be careful.  There's some tricky stuff in Mac OS X having to do with
this.  It was a galaxy long long ago and far far away, so I forget
details and even the problem project, but probably what's happening is
that you really want to pull in a BIND-specific library because libc
doesn't have it but that library does.  IIRC, of course.  YMMV.

The library that has res_9_init is /usr/lib/libresolv.9.dylib. I  
don't know what the purpose of res_init (or res_9_init) in GNU Emacs  
is. If it's needed with some real and needful functionality then /usr/ 
lib/libresolv.9.dylib is probably the right choice and the Fink  
team's "hack" with -D__BIND_NOSTATIC should be omitted. /usr/lib/ 
libresolv.9.dylib has 180 functions. Programmes that use /usr/lib/ 
libresolv.9.dylib:

/usr/sbin/kadmin        /usr/sbin/krb5kdc
/usr/sbin/kadmin.local  /usr/sbin/ktutil
/usr/sbin/kadmind       /usr/sbin/lookupd
/usr/sbin/kdb5_util     /usr/sbin/nmbd
/usr/sbin/kprop         /usr/sbin/smbd
/usr/sbin/kpropd        /usr/sbin/swat
/usr/sbin/krb524d       /usr/sbin/winbindd

A sym-link /usr/lib/libresolv.dylib exists. So I am starting to think  
that the cause for the undefined symbol _res_9_init must be a  
different one ...

Re: 23.0.50; Undefined symbol: _res_9_init

Hello!

Comparing old configure.in with the recent version, I see that from  
res_init was removed from a for loop:

	for ac_func in gethostname ... res_init ...
	do
	...
	done

The recent version of configure.in does not have res_init. Does this  
mean that no tests for res_init() are performed?
