* src/vcg.h (graph_s): color, textcolor, bordercolor are now

enum color_e.
* src/print_graph.c (print_graph): Initalize graph.layoutalgorithm
to `normal'.
* src/reader.c (parse_token_decl): Initialize token with tok_eof.
* src/lex.h: Adjust prototype.
(token_t): Add `tok_undef'.
* src/lex.c (struct percent_table_struct): Retval is now a token_t.
(parse_percent_token): Now returns token_t.
Add default statement in switch.
(lex): Separate `c' as an input variable, from the token_t result
part.
(unlexed): Is a token_t.
