41     # 2.0.51, we now have support for installing libraries to lib32/lib64
42     # to accomidate the needs of multilib systems. It's no longer a good idea

44     # where lib is named directly with $(get_libdir) if possible.
45     #
46     # Jeremy Huddleston <eradicator@gentoo.org> (23 Dec 2004):
