	Which version of MacOS are you running? Though I suppose a
better question might be, where did the files in /usr/include come
from? Also, which version of ColdSync are you trying to build?

	For what it's worth, ColdSync 2.2.5 compiles for me (not
cleanly, but still) under MacOS 10.2.

	Yes, you're probably right that the compiler isn't finding a
definition of 'u_char'.

	Looking at the code, it looks as though <arpa/nameser.h> is
included to make inet_ntop() work under Solaris. Under MacOS 10.2, the
man page fore inet_ntop() says to use:

	#include <sys/types.h>
	#include <sys/socket.h>
	#include <netinet/in.h>
	#include <arpa/inet.h>

All four of those files are already included. So you may want to
comment out the #if HAVE_INET_NTOP...#endif block, and see whether
that fixes things.
	If it does, then future releases of ColdSync should probably
use something like
	#if HAVE_INET_NTOP && defined(sun)
or some such.
