Problems building Kawa with gcj

[Will Newton <wnewton at cmedltd dot com>]

I'm having problems building Kawa on Debian (unstable) using gcj.

Configuring as per the docs:

./configure --with-gcj --without-awt --without-swing --prefix=/usr

And compiling, the build fails because the option -DPIC is used for gcj and 
there is no --main option [1]. So I tried to disable PIC to see where that 
get's me. Configuring thus:

./configure --with-gcj --without-awt --without-swing --prefix=/usr 
--without-pic


Now I get as far as building the kawa1 binary, where I get a load of 
unresolved symbols [2]. The files being linked to all appear to exist. Maybe 
this is some kind of libtool issue? I can attach the full build log is 
someone might find it useful.
