We do that because the declaration of this type, which is local to
src/tgba/tgbasafracomplement.cc has a member in an anonymous
namespace, and some versions of g++-4.2 issue a very annoying
warning about this legitimate code.  See Bug 29365 on GCC's
Bugzilla.  Report by Silien Hong <silien.hong@lip6.fr>.

* src/tgba/tgbasafracomplement.hh (safra_tree_automaton): Do not
forward declare.
(tgba_safra_complement): Use void* instead of
safra_tree_automaton*.
* src/tgba/tgbasafracomplement.cc: static_cast void* to
safra_tree_automaton* anywhere needed.

Such changes should not be pushed to master before they are finished
(this doesn't pass distcheck).

* src/ltlvisit/contain.cc (reduce_tau03_visitor): Remove
the stronger rules for R and M.  They were wrong.
* src/ltltest/reduccmp.test: Test a simpple counterexample.

a R (b R c) = a R c if a implies b.
a R (b M c) = b M c if b implies a.
a M (b M c) = b M c if b implies a.
The latter rule was fixed from an incorrectly copied&pasted
