I didn't realize earlier, but I do have jar files in pljava/target. I
was looking earlier only at the top target directory

I renamed jni.h to jni.h.txt (as I'm sure that some email clients will
not like the .h extension) and attached here.

The ${java}/include/win32/jni_md.h is inline below:

#ifndef _JAVASOFT_JNI_MD_H_
#define _JAVASOFT_JNI_MD_H_

#define JNIEXPORT __declspec(dllexport)
#define JNIIMPORT __declspec(dllimport)
#define JNICALL __stdcall

typedef long jint;
typedef __int64 jlong;
typedef signed char jbyte;

#endif /* !_JAVASOFT_JNI_MD_H_ */

I must say that I'm impressed with your knowledge. I've been writing
Java code for a very long time now, and never even knew that there are
.h files in ${java}/include
