To avoid a crash on some platforms (like Darwin 9) provide a buffer to realpath(3). Darwin 9 (last PPC target) documents realpath needs to be given a buffer to the resolved_path argument large enough to hold PATH_MAX bytes. With NULL argument it crashes. Solaris makes no mention of resolved_path to be allowed NULL, yet recent versions accept it and malloc(3) accordingly. Because the documentation explicitly mentions PATH_MAX being the limit to what realpath(3) would write in resolved_path, switching to a static buffer here doesn't limit resolution compared to dynamically allocating a buffer by realpath(3). While this change requires a bit more space on the stack, it avoids a malloc/free sequence, and allows successful operation on (older) platforms that lack support for dynamically allocating a return buffer in realpath(3).
