asio vs windows

test.h

// 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
struct MessageThing
{
    void SendMessage(int foo);
};


// message.cpp file
#include "message.h"
#include <asio.hpp> // let's say we need Boost asio for something

void MessageThing::SendMessage(int foo)
{
   // whatever
}
