I've been doing some Jython performance investigation recently so I
was intrigued by the above statement.  I tried:

% python translate.py -b jvm --batch targetpypystandalone.py

which failed at:

I was able to translate targetnopstandalone to Java so it seems to
work a little, but obviously there is a big difference between that
and PyPy. :) Trawling the IRC logs I found:

[20:39] <antocuni> fijal: unfortunately pypy-jvm does not compile 
out of the box
[20:39] <antocuni> you have to manually patch two lines in rbigint 

Is this still true?  Is the patch available somewhere?
