Sure.  I updated from CVS::HEAD and rebuilt lexed_tokens, which works
correctly (like Boost 1.33.1) again.  I also rebuilt my static analysis
tool (it's basically a hacked up version of lexed_tokens) and analyzed
my sources and got the same answers as before (minus the "invalid
character" error).

Thanks!
