I couldn't actually reproduce this problem here - libgcj.so is linking
libgcc_s.so already, so no undefined symbols.

Aah, we definatly want to use the shared libgcc (yay!), and heres a patch
to do so. This brings the size of a hello-world down from 90K to 19K on
i686 (4K stripped). Cool!

Unfortunately something seems to have broken "gcj -static". I'm getting:

 /home/bryce/gcc/lib/gcc-lib/i686-pc-linux-gnu/2.97/collect2 -m elf_i386

I'm not sure if this is caused by my patch or if it was broken before.
Any ideas?
