Well, first it has to work. It seems either configure.jam is broken or the new 
link.jam has some errors.
When I use (from line 127 in configure.jam, see diff attached)
  
  for local t in $(targets) 

I get 

/home/hunold/src/devel/boost-git/tools/build/v2/build/configure.jam:126: in 
try-build
rule object(property-set)@878.actualize unknown in module configure
/home/hunold/src/devel/boost-git/tools/build/v2/build/configure.jam:164: in 
builds-raw

(full log attached, too).

If I only use

    for local t in $(targets[2-])

compilation works, but symlink checks are broken. I think I'm missing 
something obvious here... The original code used  $(targets[2-]) and was 
factored out into try-build by Steven. Have to think about that and take a 
closer look...

Well, the behaviour is to create symlinks for individual files, too. 
Unfortunatly, the non-symlink fallback is to create copies.

I think that a separate solution providing either symlinks or forward-headers 
using link.jam when symlinks are possible would be best.  Especially if a 
feature controling this is provided. So the end-user can choose between 
symlinks and Qt-style forward headers.

I'm runinng short on time, so do not expect new patches from me.

Yours,

Jürgen
