Dear all,

the recent commit 9aa72c implements some changes in order
to reduce the need of runtime linking. First, libdl is
tried only if PAM is asked for, and only for executables
using that service.

Secondly, linking with libnsl, libresolv, and libsocket
is conducted more cautiously, thanks to AC_SEARCH_LIBS.
The preparatory commit 78079c implemented alternate use
of getaddrinfo() for resolution in "ifconfig/changeif.c"
and "libinetutils/localhost.c". This relieves OpenSolaris
from accessing libresolv, so my standard bouquette of seven
operating systems are know building cleanly with noticeably
reduce linking, but we should be observant on some older
border case systems in future release test builds.

Regards,
  Mats
