Thank you very much for your work on this problem, Kiyo! I've worked in 
the past days on setting the qemu image to a chroot environment for 
etch, and it seems that i should do the patches to remove fastjar, zlib 
& boehm first, as currently just the configure run takes about an hour 
on my machine, and compiling the class library with ecj more than three :/

Thank you for the patch. I'll give a go to s_j's patch as soon as I've 
turned configure back into something more manageable tonight.

off the top of my head, i'd guess ffi changes.

that's on my list to get fixed today.
