You might want to post to the Boost build list to get further details 
and answers <http://boost.org/more/mailing_lists.htm#jamboost>.

Bjam does the parsing entirely on its own. Some details in: 
<http://engineering.meta-comm.com/resources/cs-win32_metacomm/doc/html/jam/usage.html#jam.usage.operation.binding.headerscan>, 
and 
<http://engineering.meta-comm.com/resources/cs-win32_metacomm/doc/html/jam/language.html#jam.language.variables.builtins.hdrscan>.

That is really weird, given that vc8 is what I used to build the 
binaries for release. Which version are you trying to build? I ask 
because the sources where restructured some time ago and we no longer 
use the "build/jam_src" location.

You might want to watch your language. This is a public forum with a 
wide range of participant ages and philosophies.
