[PATCH] Make BUILD_BUG_ON fail at compile time.
Force a compiler error instead of a link error, because they are easier to
track down. Idea stolen from code by Jan Beulich <jbeulich@novell.com>
If the argument to BUILD_BUG_ON evaluates to non-zero the compiler will do:
t.c:6: error: size of array `type name' is negative
(surprised that gcc doesn't have an extension for this)
