10.4.4.

Beats me.  Either they came pre-installed with my Mac (a pretty fresh 
one, just bought a few weeks ago), or they were installed by the 
XCode 2.2 installer I downloaded from Apple yesterday.

Oops, sorry I forgot to mention that -- it's 2.2.5, listed as the 
most recent stable release if I understood the ColdSync pages 
correctly.

Hmm, good to know.  You probably don't have gcc 4, though; I wonder 
if that might be the critical difference?

The man page in 10.4 agrees.

Yes, that does do it!  I had to give coldsync.c the same treatment.

Makes sense to me.

Now, I'm just getting errors in config.c (plus a zillion warnings elsewhere):

config.c: In function 'get_hostaddrs':
config.c:1013: error: storage size of 'ifconf' isn't known
config.c:1061: error: invalid application of 'sizeof' to incomplete 
type 'struct ifconf'
config.c:1093: error: invalid application of 'sizeof' to incomplete 
type 'struct ifreq'
config.c:1093: warning: division by zero
config.c:1122: error: dereferencing pointer to incomplete type
config.c:1123: error: dereferencing pointer to incomplete type
config.c:1145: error: dereferencing pointer to incomplete type

Best,
