C++ backend: Skeleton files broken with user-defined tokens

[andreasabel]

Prg. Program ::= Name Name ;
token Name letter+ ;

The --cpp-nostl backend produces this Skeleton.C:

#include "Skeleton.H"

void Skeleton::visitProgram(Program *program) {} //abstract class

void Skeleton::visitPrg(Prg *prg)
{
  /* Code For Prg Goes Here */

  visitName_(prg->name_1);
  visitName_(prg->name_2);
}
void Skeleton::visitName(Name p)
{
  /* Code for Name Goes Here */
}
...

Note the extra underscore in calls visitName_.
I think the (quite ugly) code implementing the skeleton generator makes the type name from the variable name name_1, but expects only names of the form name_ without trailing number.

Lines 264 to 272 in e5574db

	--The visit-function name of a basic type
	funName :: String -> String
	funName v =
	if "integer_" `isPrefixOf` v then "Integer"
	else if "char_" `isPrefixOf` v then "Char"
	else if "string_" `isPrefixOf` v then "String"
	else if "double_" `isPrefixOf` v then "Double"
	else if "ident_" `isPrefixOf` v then "Ident"
	else toUpper (head v) : init (tail v) -- User-defined type
