FreeBSD-5.1 problem identified

[edscott wilson garcia]

The problem might also affect other xfce4 elements besides xffm. I
figured out the problem with FreeBSD-5.1 (which *might* be affecting
xfce4-panel, xfce4-session, xfdesktop and xfwm as well). Apparently the
sigaction() function does not work to change the default action of
SIGTERM (and maybe other signals), but the simplified version signal()
works fine. So that by using (in configure.ac):

AC_CHECK_FUNCS([sigaction])
AC_CHECK_FUNCS([signal])

and  

putting in code like:
#ifdef HAVE_SIGNAL
    signal(SIGUSR1, TuboSemaforo);
#else
    sigaction(SIGUSR1,&act,NULL);
#endif

xffm with all it's components is now working like a charm in
FreeBSD-5.1.

The other files that also use sigaction() are xfce4-panel/main.c,
xfce4-session/main.c, xfdesktop/main.c and xfwm4/main.c.

If anybody has a powerful reason why I should not fix them as well, I
will go ahead and do so in a few hours.
