GCJ 3.3.1 and JNI working under Cygwin?

For the first command I get:

$ gcc -I/cygdrive/c/j2sdk1.4.2/include/ 
-I/cygdrive/c/j2sdk1.4.2/include/win32/ -I. -c JNITest.c
In file included from /cygdrive/c/j2sdk1.4.2/include/jni.h:27,
                  from JNITest.c:8:
/cygdrive/c/j2sdk1.4.2/include/win32/jni_md.h:16: error: syntax error 
before "jlong"
/cygdrive/c/j2sdk1.4.2/include/win32/jni_md.h:16: warning: data 
definition has no type or storage class

I'm not quite sure what goes wrong...
