My patch removes the following:

   /* Warn about assigning a floating-point type to an integer type.  */
     if (TREE_CODE (TREE_TYPE (expr)) == REAL_TYPE
         && TREE_CODE (t) == INTEGER_TYPE)
       {
         if (fn)
           warning (OPT_Wconversion, "passing %qT for argument %P to %qD",
                    TREE_TYPE (expr), argnum, fn);
         else
           warning (OPT_Wconversion, "converting to %qT from %qT", t, TREE_TYP\
E (expr));
       }

That is where the conflict is going to appear but don't worry too much
about it, the update to my patch is simple. Just let me know when your
patch is in, so I can update and re-test mine.

Cheers,

Manuel.
