Unfortunately, kaffeh needs to be able to read classes from JAR files 
like glibj.zip in order to create corresponding headers.

There is a way out, of course: rewriting the remaining two dozen files 
in libraries/clib/native to use JNI rather than KNI. Then we could do 
away with kaffeh completely, and just use gjavah/javah/gcjh, etc.

If you want to give it a shot, I'd suggest starting with 
java_lang_String.c (just one method there), and pushing the 
corresponding generated header file in include/Makfile.am to the JNI 
header generation. The rest should be rather, as well.
