Determining whether compilation is possible on Windows or another system

I am currently developing a cross-platform C application . Is there any compiler macro that is only defined at compile time on Windows, so I can #ifdefspecify some specific Windows * include?

A typical example is the choice between WinSock and Berkeley socket headers:

#ifdef _WINDOWS
   #include <winsock.h>    
#else
   #include <sys/socket.h>
   #include <netinet/in.h>
   #include <sys/un.h>
   #include <arpa/inet.h>
   #include <netdb.h>
#endif

So I'm looking for something like a _WINDOWS macro .
