Subject: [PATCH] Merged revisions 81359-81361 via svnmerge from
 svn+ssh://pythondev@svn.python.org/python/branches/py3k

........
  r81359 | victor.stinner | 2010-05-19 19:00:07 +0200 (mer., 19 mai 2010) | 4 lines

  Issue #8663: distutils.log emulates backslashreplace error handler. Fix
  compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if stdout
  is not a TTY).
........
  r81360 | victor.stinner | 2010-05-19 19:11:19 +0200 (mer., 19 mai 2010) | 5 lines

  regrtest.py: call replace_stdout() before the first call to print()

  print("==  ", os.getcwd()) fails if the current working directory is not ASCII
  whereas sys.stdout encoding is ASCII.
........
  r81361 | victor.stinner | 2010-05-19 19:15:50 +0200 (mer., 19 mai 2010) | 2 lines

  Oops, add the new test_log.py for distutils test suite (missing part of r81359)
