    actually realpath == abspath on most platforms where symlink is not implemented.

    Changed.

    Why would sys.executable be a directory?

    Yes, it is the issue bpo-7774.

    The patch proposed on msg98284 should fix sys.executable being a directory.

    Tarek, if you implement the patch for sysconfig, add a note regarding the dir hack:
    # XXX : see bpo-7774

    Fixed in r78828 and r78829 (py3k), except for the part related to bpo-7774.

    (It was turning buildbots red, after Victor fixed bpo-3137)
