Last attempt to hack around the winsock issue before I give up

Refs #7769

Code/Mantid/Framework/Kernel/src/RemoteJobManager.cpp

 // HACK! Workaround for Poco headers trying to include both winsock.h and winsock2.h
 // If this actually works, I'll see if I can get on an actual Windows machine and
 // try to sort out a better solution
-#ifdef _WIN32
+#if defined(_WIN32) || defined(WIN32)
+  #warning "Including winsock2.h!!"
   #include <winsock2.h>
 #endif
