In libstdc++-v3/config/io/basic_file_studio.cc:
@@ -246,7 +246,11 @@
 #ifdef FIONREAD
 // Pipes and sockets. 
 int __num = 0;
+#ifdef __MINGW32__
+ int __r = ioctlsocket(this->fd(), FIONREAD, (u_long*)&__num);
+#else
 int __r = ioctl(this->fd(), FIONREAD, &__num);
+#endif
 if (!__r && __num >= 0)
 return __num; 
 #endif 
The above change is probably wrong (at least untested).

The JNIIMPEXP which is defined as 
 __declspec(dllexport)
causes this. If you re-declare the three methods (JN_CreateVM etc.) as
extern jint JNICALL, then this will work.
