This is just an oversight on our part.  These friend declarations are
added by some code in Makefile.am -- care to take a stab at fixing
them?  It might involve a little rearrangement since now Field.h will
probably need to refer to jni.h.

I think the functions in gcj/field.h have subtly different names.  The
_JNI_ versions are part of our implementation of JNI.  The ones in
gcj/field.h are part of CNI.
