I say maybe. I personally am the wrong person to talk to, i hate this aliasing issue, i saw so-and-so many *BSD and more commits fly by where code that worked started breaking, and had to be circumvented by doing memcpy(), sheer grazy. They _broke_ the system. And i am yet to see the advantages. (From my simple userspace programmer's point of view, with a bit of assembler, in earlier times.) So if an intermediate cast to "char*" gets you going, or "void*", why do that at all? It _will_ fit in the size of sockaddr_storage, it will have the proper alignment, i want to cast it. Period. "POSIX-compliant compilers" (-std=c99) should not fail in theory. Issue 7 is based upon ISO C99.
