hi,

here's a simple test case of the binary compatibility problem.

1. compile the attached file on a pre-bind9resolver box.
	% cc a.c
	% objdump -x a.out|grep _res
	08049bc0 g     O .bss   000001bc _res
	% ./a.out
	%

2. run it on a post-bind9resolver box.
	kaeru% objdump -x /lib/libc.so.12.120|grep _res\$
	000b5240 g     O .bss   00000200 _res
	kaeru% ./a.out
	zsh: segmentation fault (core dumped)  ./a.out
