    # Regression test for gh-2999 and gh-2915.
    # There are several packages (nose, scipy.weave.inline, Sage inline
    # Fortran) that replace stdout, in which case it doesn't have a fileno
    # method.  This is tested here, with a do-nothing command that fails if the
    # presence of fileno() is assumed in exec_command.

    # The code has a special case for posix systems, so if we are on posix test
    # both that the special case works and that the generic code works.

    # Test posix version:
    with redirect_stdout(StringIO()):
        with redirect_stderr(TemporaryFile()):
