IMHO there are still problems with strncat(3).

If you use something like that:

	strncat(buf, string, sizeof(buf) - 1);

why not just use:

	strncpy(buf, string, sizeof(buf) - 1);

because correct form is:

	strncat(buf, string, sizeof(buf) - strlen(buf) - 1);

There is also syntax error here:

	strncat (ib_prefix_msg_val, MAXPATHLEN, ib_prefix_msg);

You also still don't add:

	buf[sizeof(buf) - 1] = '\0';

after all strncat(3)s.

This was in first patch:)

IMHO if you want to keep portability, just add some BSD-licensed strlcat(3)
and strlcpy(3) implementations to firebird's code and use it, because
strncat(3) is really fucked up.
