[pypy-dev] pypy-jvm translation, patch

[Marek Paška]

Hi,

today, I tried to translate pypy-jvm, but the translation failed with
the trace below. The following patch makes the translation to be
completed:

Index: pypy/translator/jvm/metavm.py

However, I am not really sure whether the patch is really correct :-)
Pypy-jvm does not work anyway, it is the problem I reported several
weeks ago:

paskma at paskma:goal$ ./pypy-jvm
'import site' failed
Python 2.4.1 (pypy 1.0.0 build 100000) on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``nothing is true''
Error calling sys.excepthook:
debug: OperationError:
debug:  operror-type: ImportError
debug:  operror-value: cannot import name 'curdir'

(Don't be confused by the build number, I am using git-svn.)
