Based on your Resin patch, I've added some things to kaffe's jni.h: the 
missing struct and a few typedefs, so that now it should be easier to build.

The main remaining problem in the passing of JavaVMInitArgs. That has 
changed between different JNI versions. Kaffe's current JavaVMInitArgs 
is somewhat like JDK 1.1's.

We'd need to decouple KaffeVMInitArgs from JavaVMInitArgs, and change 
our command line argument parsing to deliver JavaVMInitArgs with a 
JavaVMOptions array, and adapt all the functions using JNI to the new 
scheme of things.

Would you like to have a go at it? I want to look into fixing argument 
parsing anyway.

cheers,
