Many (but not all) Boost libraries carry this license:

//  Permission to copy, use, modify, sell and distribute this software
//  is granted provided this copyright notice appears in all copies.
//  This software is provided "as is" without express or implied
//  warranty, and with no claim as to its suitability for any purpose.

There are already many files in libstdc++ with this license (for
example include/bits/boost_concept_check.h) so it seems that this
is OK. It is still a good idea to ask for permission, and possibly
check with the FSF before copying anything.
