Suggestion from web: correct work with struct sockaddr_in

Correctly handle this source from a user on all architectures/compilers/optimizations:
```c
#include
#include
#include
#include

int main(int argc, char **argv) {
struct sockaddr_in addr;
memset(&addr, 0, sizeof(addr));
addr.sin_family = AF_INET;
addr.sin_addr.s_addr = htonl(INADDR_LOOPBACK);
addr.sin_port = htons(123);

int mysocket = socket(AF_INET, SOCK_STREAM, 0);
connect(mysocket, (struct sockaddr *)&addr, sizeof(struct sockaddr));
return 0;
}
```

No source file, test, or entry point is named. Start by locating the RetDec code that handles this sockaddr_in example, then reproduce the supplied program across architectures, compilers, and optimization levels; done means it is handled correctly in each requested configuration.
