Sorry - my bad. I go and make a post then break the CVS. Typical :-)
I've fixed it now (forgot to add a new class to CVS).

I did try this, and I got:

jc1: error: unrecognized option`-fjini'

Could there be something funky about the GCJ 3.3.3 build in Debian? I'm
just using their packaged up version.

I get no errors up until linking the executable at the very end, where I

lib/ undefined reference to
`org::eclipse::swt::internal::gtk::OS::gtk_window_move(int, int, int)
collect2: ld returned 1 exit status

It seems to be for every method that should be in swt-pi.jar (I'm
compiling the sources from swt-pi.jar, swt-mozilla.jar and swt.jar together 
into one .so - shouldn't be any problem with this as far as I can see,
the only reason they are separate jars in the first place is for IBMs licensing

Thanks, and thanks for the help! GCJ is a cooler project :-)
