Generated files for C++ do not throw parse_error

[MagicWinnie]

I am running following command for generation:
bnfc --cpp -l -m -o src/Stella -p Stella Stella.cf

I get this Test.C file:

...
  Stella::Program *parse_tree = NULL;
  try {
  parse_tree = Stella::pProgram(input);
  } catch( Stella::parse_error &e) {
     std::cerr << "Parse error on line " << e.getLine() << "\n";
  }
...

But it does not throw parse_error when given a faulty input, in fact, it just prints following:

error: 1,1: syntax error at <....>

I found this PR that added parse_error: #288

But the file source/src/BNFC/Backend/CPP/STL/CFtoBisonSTL.hs is absent in 2.9.5 version, I assume BNFC uses somehow the C related stuff to generate the .y file. This is the generated Stella.y file that I get:

...
void yyerror(YYLTYPE *loc, yyscan_t scanner, YYSTYPE *result, const char *msg)
{
  fprintf(stderr, "error: %d,%d: %s at %s\n",
    loc->first_line, loc->first_column, msg, Stellaget_text(scanner));
}
...

I assume that here should be something like throw Stella::parse_error.

That CFtoBisonSTL.hs file containing the parse_error call was removed in #351

Fixed in #494
