Subject: [PATCH] bug #140: Remove -fno-strict-aliasing
Remove -fno-strict-aliasing (this is not required because gssproxy
is mostly a good ISO C99/C11 citizen) and replace it with
-Werror=strict-aliasing to ensure that if *anything* creeps up
the build will just fail (this requires in gcc4.x's case the
use of -fstrict-aliasing, too).
