It's not so easy :-( I've regenerated the files as part of this commit:

2004-01-26 12:16 vladimir_prus

        * graphviz_digraph_parser.cpp, graphviz_graph_parser.cpp,
        graphviz_parser.yy: Fix (or rather workaround) the bug which caused
        second reading of graphviz file to fail. Looks like the parser is
        not reenterant.

        Patch from anynymous user.

so if we revert the files back, we'll introduce back a bug. I've just
regenerated the files again and Jeffrey's problem is gone. Guess we'd need to
#define YY_NO_UNISTD_H
to fix the other problem. I've added that to Jamfile and the files seems to
still build.

Should I commit the regenerated files and Jamfile changes?

How the new parser will be implemented?
