Comment (by Mathieu Champlon <m.champlon@…>):

 I added a test case to verify that the following code fails to compile
 {{{
 #define BOOST_PROTO_MAX_ARITY 10
 #define BOOST_PHOENIX_LIMIT 20
 #include <boost/phoenix.hpp>
 }}}
 because in case BOOST_PROTO_MAX_ARITY has been previously defined (for
 instance by including another boost library) there isn't much that can be
 done but #error'ing to the user.

 boost_phoenix_7166.patch includes both the test case and the fix already
 included in the previous patch.

 Cheers,

 MAT.
