Subject: [PATCH] strict aliasing
workaround strict aliasing warnings on individual files rather than
forcing the whole build with -fno-strict-aliasing
http://bugs.gentoo.org/155906
note that we leave the logout.c and logwtmp.c warnings alone as the
code path that invokes the warning should not be executed when the
warning is applicable.
