Now this statement I don't agree with. (And by that I don't mean I assume it to be false.) I didn't start writing the patch because I like C99 so much. In fact, in my opinion it introduces some possibilities I'd rather not have in C because people might actually use them. But by default the Sun cc complains about void-pointer arithmetic and I feel awkward to force the compiler to accept broken code. Maybe Rene Scharfe's method (as used in the patch to git-tar-tree) is a good way around it? There are no explicit casts involved and standard- compliant compilers like it, too. The downside is that you have two variables for the same thing/memory.
