Log message:
        (_AC_PROG_CXX_EXIT_DECLARATION):
        Remove `#include <stdlib.h>' from the list; we should never
        make confdefs.h include <stdlib.h> or <cstdlib>, because the
        resulting namespace pollution would cause other tests to fail.
        Configure scripts run with some older versions of g++ and HP's
        aCC would fail due to such an #include.  Problems reported by
        Matthew Mueller in <http://bugs.debian.org/120704> and by
        Keith Bostic in
        <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
        In the test, use the test declaration before including <stdlib.h>,
        as that's closer to how it'll be used.
