Hi,

There were a lot of discussions about MPL recently, and I created a few pull 
requests to address issues:

https://github.com/boostorg/boost/pull/39

Invoke 'headers' target before building testing tools. Note that several 
testers are currently failing to run because of this problem. Since this 
affects the testing process, I'd appreciate if someone familiar with it could 
take a look.

https://github.com/boostorg/boost/pull/38

Add MPL.Core tests to the test report. These tests are currently not run by 
testers.

https://github.com/boostorg/mpl/pull/12

Move a misplaced header from MPL to MPL.Core to resolve circular dependency 
between the two.

I believe the first PR is especially critical. Could someone with permissions 
merge these?

Thanks.
