Do you know when it started happening.. I know that at one point before 
the 1.32 release there was a change that broke the regex that's used for 
the scanning in BBv1. Somehow the tabs in the regex got translated to 
spaces which made for a very picky scanner :-(

PS. Let that be a warning to all.. If you see real TABS in the BB .jam 
files *don't* "fix" them. They are usually intentional.
