That's not so. When file is modified on server, CVS merges the changes from 
server to your local copy.

Ok. In the meantime, I've comitted new version of libs/graph/build/Jamfile.v2 
as well as libs/graph/src/graphviz_lex.ll and 
libs/graph/src/graphviz_parser.yy. This change should really make BGL build 
working again --- turns out it worked only in my local copy.

Great. That would be cool.
