Approved - with a few minor changes, see below - please apply.

[optional]: This variable could be moved inside the if statement
starting at line 672, localizing it, if the statement was changed to:

  if (old_sec == NULL)
    {
      bfd_boolean override = FALSE;

      if (attr & ~ ssect->attr)
        {
        ...
        }

      if (!override)
	attr |= ssect->attr;
  }      

I feel that the code looks neater this way.

I would appreciate it if you could add a space between the '&' and the
'~'.  These are separate operators and should not be juxtaposed like
that.  I know that this is not part of your original patch, but since
we are modifying this area of code, I think that it would be a good
idea to clean this up.

Since the new attributes are going to be ignored, we should change the
warning message appropriately.  Something like:

	      as_warn (_("ignoring setting of incorrect section attributes for %s"),
