Thanks for the tip. However, it seems a little brittle. If at any point in 
the future someone adds dependencies to MyExe without adding them to 
$(myfiles), the build-id won't always be updated when the exe is. I could 
put a comment by the exe rule in the jam file, but this may not stop someone 
adding <library>somelib to the requirements of the project at the other end 
of the long Jamfile.

Any further suggestions?
