It's GPLv2+exceptions:

The source code of Threading Building Blocks is distributed under version 2
of the GNU General Public License, with the so-called "runtime exception,"
as follows (or see any header or implementation file):

   As a special exception, you may use this file as part of a free software
   library without restriction.  Specifically, if other files instantiate
   templates or use macros or inline functions from this file, or you compile
   this file and link it with other files to produce an executable, this
   file does not by itself cause the resulting executable to be covered by
   the GNU General Public License.  This exception does not however
   invalidate any other reasons why the executable file might be covered by
   the GNU General Public License.

I believe it's the same exception as the one in GNU libstdc++,
