Re: [boost] [chrono] Dependency on math?

The latest dependency report shows chrono as having a dependency on math.

See http://www.pdimov.com/tmp/report-develop-3b5a9f4/module-overview.html

math is really big. In testing bpm, an install of timer (which depends on chrono) slowed noticeably when it got to math. Presumably the build is also much slower, although I haven't tested that yet.

Is the math dependency really needed?

The dependency is on || * from || * from || Of course, I can duplicate this function for my specific case, but I think this is not a good approach. I could suggest to move this file to integer which is at level 2 :) Reducing dependencies could improve compilation times and it could surely be the case here as chrono needs only a specific gcd, but I will not expect too much gain.
