Dependencies not handled correctly

Reported by: s.d.c.west@… Owned by: eric_niebler
Milestone: To Be Determined Component: accumulator
Version: Boost 1.52.0 Severity: Problem
Keywords: Cc: eric@…


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.
