Now the compiler package works. The patch passes regrtest with "-u all" option and "-u compiler" option (except test_frozen.py). The patch is against latest p3yk branch HEAD. The last patch accidentally included some test code in test_compiler.py (and which is committed to the svn) so this patch includes fix for that. 
Ah, Guido, when you committed the patch (previous version) last time, you did not add Lib/test/test_keywordonlyarg.py so, this time, don't forget to add it :) Also, last time when we talked, I think you said that the patch makes some test case fail on your laptop machine. You might want to check that.
