hi,

openvswitch has the following CTASSERT equivalent, which doesn't
require __COUNTER__.

#define OFP_ASSERT(EXPR)                                                \
        extern int (*build_assert(void))[ sizeof(struct {               \
                    unsigned int build_assert_failed : (EXPR) ? 1 : -1; })]

any comments from C lawyers?
