While trying with 1.1.7, I noticed one more interesting reports
in http://www.kaffe.org/pipermail/kaffe/2004-March/097294.html
(yes, always I got important information from Helmer, thanks!)
which said, arm-jit might not work with gcc-3.x, so I also change
compilers to 2.95.

But, first I got very funny result saying some of java codes
can not be compiled. I went back to bed, and second try, same
result. Then, this afternoon (JST), I finally understand, I am
fully silly ;-< I have to use 'glibj.zip' coming from the same
version of distribution. (I used much younger version of glibj.zip
for this compilation)

The compilation was finished, but looks like it does not work.
It stops at the same point (SIGSEGV for 'detectStackBoundaries').

For this part, I found this 'bug' was introduced with patch file
called 'hdrcleanup-2.6'. Experience tells, cleanup sometimes drop
several valuable things ;-<

Thanks, if you are really interested, I will send you working copy
of QEMU with bootable kernel and disk images.
