c quoi ce vieux troll ? (non seulement pas justifié, mais en plus completement hors sujet)

sinon pour la licence utilisée par la STL de GCC, c'est du GPL avec l'exception suivante :

// 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.
