System: NetBSD rumolt.teuto.de 1.4ZD NetBSD 1.4ZD (RUMOLT) #0: Fri Jun 16 07:05:23 MEST 2000 martin@rumolt.teuto.de:/usr/src/sys-i4b/arch/i386/compile/RUMOLT i386


>Description:

When trying to build pkgsrc/net/rsync on a machine with IPv4 only kernel,
the autoconfiguration fails, since it supposes a bug in getaddrinfo.

>How-To-Repeat:

s.a.: it tries to compile this testprogram (debug output inserted by me), and
fails at inet6 = 0, inet 4 = 2, because the loop for inet6 never has been
done.
