It's quite easy actually. Before doing anything, bjam prints

...updating XXX target...

in the end it should print 

...updated YYY targets....

If YYY is less then XXX and there were no skipped targets, we're in problem. I 
think I'd rather explain the bug I've introduced last week and fixed 
recently.

Whenever each target is built, all dependents of this target are notified, and 
when all outstanding dependencies of a given target sent notification, the 
target itself is built. The current version of bjam has certain Perforce 
change merged in --- and each target with #includes have another "internal" 
target which represent included targets. The problem was that when "internal" 
target was built, the code was failing to send correct notification. As the 
result, dependents were never considered ready.

And when "-a" was present, *all* internal nodes were marked for updating, and 
consequently, nothing was ever considered ready for updating.

I'm hoping that's the last bug in my changes of dependency scanning.
