For the time being, this include does nothing evil.

Well, I use the new <implicit-dependency> feature now.
If you look at qtlib/Jamfile, I use implicit dependencies like

use-project /gui : lib/gui ;
<implicit-dependency>/gui

to progate generated includes to main and the other libs.
When I move use_project after project, I get

error: Recursion in main target references

(see attached file out.txt below). Or am I missing something ?

mmh, it used to work _before_ the restructuring.
But I can tell for sure because I didn't do a complete rebuild when you 
introduced <implicit-depency> and I first used this.

So you are right , this is most probably broken all the time.

Yours,

Jürgen
