Running 'bootstrap' to build boost-1.56.0 with VS2005 SP1, I believe I 
have encountered the same problem described here:
http://lists.boost.org/boost-build/2014/01/27304.php

In this thread, the OP put the problem down to a misconfigured compiler, 
but I'm not sure this is the case. I think there are two issues here. 
Firstly, IO_REPARSE_TAG_SYMLINK is not defined at all in the version of 
the Platform SDK that accompanies VS2005. Secondly, 
FSCTL_GET_REPARSE_POINT is only defined if _WIN32_WINNT is defined to 
0x500 or greater. However, when compiling Boost build, _WIN32_WINNT 
isn't being defined at all.

A trivial patch (attached) fixed the above issues for me, and gets 
'bootstrap' working under VS2005 SP1. I am aware that you have to 
support a vast number of different compilers across several platforms, 
so hopefully there is enough information in this e-mail for you to fix 
the problem should the patch not be to your liking.

Thank you for all your hard work with Boost,

Dave Stacey.
