Strange. lvalp should have the type YYSTYPE, which should be declared in
yystype.h. Would you mind running

   g++ -save-temps -ftemplate-depth-50 -DGRAPHVIZ_DIRECTED=0 -I../../.. -g 
   -c graphviz_graph_lex.cpp

and looking at preprocessing results (in graphviz_graph_lex.ii) and
determining the real type of 'yylex' function parameter and 'lvalp'
variable?
