#7409: Dependencies not handled correctly

 Reporter:  s.d.c.west@…          |       Owner:  eric_niebler
     Type:  Bugs                  |      Status:  new         
Milestone:  To Be Determined      |   Component:  accumulator 
  Version:  Boost 1.52.0          |    Severity:  Problem     
 Keywords:                        |  
----------------------------------+-----------------------------------------
 To test the dependency system of the Accumulators library, I tried adding
 an alternative implementation of the 'count' feature, which I called
 'alt_count' (see attached file count.hpp which includes the alternative
 version). To express that alt_count defines the same feature as count, I
 included the following:

 template<>
 struct feature_of<tag::alt_count>
   : feature_of<tag::count>
 {
 };

 I then ran a test program (attached), which should compute the mean of the
 numbers {1,2}, but returns -nan.
