No, it doesn't.  The advertising clause was

     * 3. All advertising materials mentioning features or use of this software
     *    must display the following acknowledgement:
     *    This product includes software developed by the University of
     *    California, Berkeley and its contributors."

The HP/SGI STL licenses don't say anything about advertising.  They are a
straightforward adaptation of the X license, of which says:

  This is a simple, permissive non-copyleft free software license,
  compatible with the GNU GPL.

RMS has already signed off on the license being OK for inclusion in a GNU

I agree that this would be necessary for users of a program built with
library code with the actual BSD license, but I don't think it is for the
STL license.  "supporting documentation" seems to me to refer to
documentation for the library itself.  But perhaps, as you say, that is a
matter for an FSF lawyer to consider.

FWIW, I'm still somewhat dubious about the change itself.  I'd rather keep
open the option of exchanging code with SGI.  But my vote doesn't count for
much.  :)
