Rusty Russell f74ae3257a cast: make sure suncc sees a constant. ... cast_const() et. al. are supposed to be a constant expression, so you can do things like: static char *p = cast_const(char *, (const char *)"hello"); Unfortunately, a cast to intptr_t and arithmetic makes suncc reject it as a constant expression. We need the cast, because (1) the expression could be a void *, so we can't just add to it, and (2) gcc complains with -Wcast-qual without it. So instead of adding BUILD_BUG_OR_ZERO, we use a ? :, which keeps everyone happy.
