Simplify setsockopt() casting workaround
On Win32, the third setsockopt parameter has type (char *) while on POSIX systems it is (void *). However, given that it is a no-op cast to go from a char pointer to a void pointer, we can cast to a char pointer (with a possible const modifier) on all platforms and satisfy the compiler.
