           hack    gcc-4.5 arm CNAME hostname lookup failure on
                   certain DNS environment (probably -ftree-ter problem)

           descr   Hostname lookup against CNAMEs by some commands fails
                   on certain DNS environments if lib/libc/net/gethnamaddr.c
                   (ping(8) etc) and lib/libc/net/getaddrinfo.c (ftp(1) etc)
                   are compiled with -O2, even though nslookup(1) against
                   the same CNAME returns proper hostname.
                   They works properly if compiled with -O2 -fno-tree-ter.
                   Also -O2 fails but -O2 -fno-tree-ter works on the following
                   test case in gcc bugzilla:
