OK so I've just been hit by my first Git SNAFU.

1) I checked out modular Boost as per 
https://svn.boost.org/trac/boost/wiki/TryModBoost
2) Changed libs/multiprecision to the develop branch also as per 
https://svn.boost.org/trac/boost/wiki/TryModBoost
3) Added some pending changes from the old SVN Trunk that I didn't commit 
before the changeover.
4) Ran the tests and everything failed, even though it was passing on SVN 
:-(

The issue was that the headers under boost/ were now *copies* of the last 
release and no longer pointers to the new "develop" code.  Interestingly 
some of the hard links were updated when I ran bjam, but apparently not all 
:-(

Running bjam -a fixes the issue, but it's a very easy trap for the 
unwary.... John.

PS, one other very annoying issue for VC++ users:

1) Open a test file.
2) Select a #included boost file, right click and select "Open document".
3) Document opens, but gives you a copy under boost/ not the "real" header 
under libs/mylib/.
4) Run away screaming after you've spent an XXX hours editing the wrong 
file....
