asio vs windows
// will this compile on windows? haha nope
// why? because asio transitively includes winsock2.h somewhere, which includes windows.h somewhere,
// which hijacks SendMessage to be SendMessageA or SendMessageW (and also means hundreds of thousands of lines
// of header includes, but that's just compilation "throughput" issue, not an error by itself)
// message.h file

void SendMessage(int foo);
