Is there a reason that the same fix that was applied to the NetBSD-1.5
and NetBSD-1.6 branches (namely, a pullup of revisions 1.13 and 1.14
of lib/libc/rpc/xdr_array.c) can't be applied to the NetBSD-1.4 branch
(other than "nobody's asked for it or tested it yet")?

I've successfully updated a 1.4.3A/i386 machine with said fix and,
though I don't have an exploit available to test it with, the system
runs just fine with the new libc.  I intend to update the compat14
package with new distfiles with this fix and the fix for SA-2002-006,
but it would be preferable if this fix was "officially" on the branch
first.
