[Boost-users] GRAPHVIZ_DIRECTED macro definition?

Hi,

In the file
        .../libs/graph/src/graphviz_parser.y

we have the following:

#ifndef GRAPHVIZ_DIRECTED
#error Need to define the GRAPHVIZ_DIRECTED macro to either 0 or 1
#endif

I couldn't locate the definition for the above macro in my boost 
installation. Do we need to define it explicitly, or am I missing 
some file(s)?

Thanks,
Soumitra
