	I was tired when I have written this mail. Of course, on NetBSD, 
sigpending always returns 0. On Solaris and Linux, it can returns -1. 
Thus, I have written :

        if (sigpending(&set) != 0)
        {
            (*s_etat_processus).erreur_systeme = d_es_processus;
        }
        else if (sigismember(&set, SIGSTART) == 0)
        {
            while(sigismember(&set, SIGSTART) == 0)
            {
                if (sigpending(&set) != 0)
                {
                    (*s_etat_processus).erreur_systeme = d_es_processus;
                }

                nanosleep(&attente, NULL);
            }
        }

and 'set' is not modified by sigpending even if I send a blocked signal 
to my process.
