Perhaps we can use the Qt4 approach. Qt4 has a general "include" 
directory which contains script-generated forward header which simply 
#include the real header using relativ paths:

Example:

QTDIR/include/QtCore/qstring.h contains:

#include "../../src/corelib/tools/qstring.h"

and everything works. Trolltech used symlinks in Qt3 where available and 
moved the headers on Win32 using some P4 magic, but I think this was a 
maintenance nightmare. The current solution is better.

It would be nice if Boost.Build could then automagically create this 
forwards instead of using a script...

Yours,
