Hi Dalibor Good thing you're still lurking! :-)

I don't think I'll be able to help improving IKVM. GNU Classpath might be easier to help with, but then I still don't have a clue how to work with GNU Classpath on Windows (Cygwin only coming with GCC 3.x, not 4.0). I haven't had the time to help myself to a true Unix environment, yet. I've got access to two Unix systems, both of which don't have GCC/GCJ installed and I have limited knowledge on unixish systems to simply know how to install additional software (if I'm allowed at all). And then I hate C/C++ and having to apply patches before I can compile some software. :-) So this means that it takes a lot of nerves to go after this. > > Since we've also heard several voices who would like the > > Batik-dependency to be optional for FOP (to reduce JAR size), I'd like > > to propose making it so by extracting the SVG support from the main > > codebase.

Oops, sorry, looks like I had the wrong idea in mind.
