What would help enormously for this would be a complete justification
for the individual fixes:

* Does a standard call for some specific declaration?  If so, which one,
  chapter and verse?

  In such a case, it will be easier get Oracle's attention so the issue
  is also fixed upstream.    (If only C++ 2011, it might be a bit of a
  tougher ride.)

* If this is a libstdc++ requirement not currently demanded by a
  standard, would there be an alternative way to fix this inside
  libstdc++?  The reason I'm asking is that the OS headers tend to be a
  moving target, and you may have to keep updating the fix to keep it
  working.

Please keep in mind that my understanding of C++ is minimal, so what may
be obvious to you might not be to me.  I'm not at all opposed to perform
fixincludes fixes, but if there are alternatives, they should at least
be considered.

Thanks.
