[Boost-build] [headers] some weird issues with hardlinks

Hi all,

I have just deployed a private build agent for testing boost.test. I 
have a problem with one of the headers not showing up.

The build I am making is just this

- checkout boost[develop]
- checkout boost.test[specificbranch]
- run b2 headers
- run b2 on boost.test regression
- rmdir /s boost folder
- rmdir /s bin.v2

The trace of the error is shown below: the header 
"boost/utility/detail/result_of_iterate.hpp" is not there, only on Win7. 
It works well for the other targets (OSX + Linux).

The funny thing is that when I run "b2 headers" from a command line, the 
header is in the right place.

The questions are:
- Am I doing things right? I thought that running b2 headers is 
sufficient for having everything under $BOOST_ROOT/boost in the right 
place. Am I missing something?
- what makes b2 think that something has to be copied or not? I can see 
in the logs hardlinks created "on demand", while I thought that running 
"b2 headers" should create all those links already.
- is there a way to avoid the creation of hard links (just a copy would 
do)? or to avoid the economic approach where they are created on demand?

The full log is located here: http://pastebin.com/raw.php?i=cgWBxhgS

Thanks!
Raffi
