Yes. The definition happens on line 8 of yystype.h.

My version of graphviz_graph_parser.hpp has the following (lines 55-58):

#ifndef YYSTYPE
typedef int yystype;
# define YYSTYPE yystype
#endif

So it looks like the test is different as well as the #define arguments
being switched around.

When I changed my lines to match your lines, I was able to get the
graphviz_graph_lex.o file, but the build chokes again when it tries to
re-run with -DGRAPHVIZ_DIRECTED=1.

Thanks for the help.
