mixing classes c++ and xs with same name!

I have started converting my c library to c++ to make use of STL.

class Laff
{
  private:
    bool          case_sensitive;
  public:
  Laff();
  ~Laff(void);

  std::string                           path;
  cdmg_ht*                              cells;
//  cdmg_ht*        layer_info;
  HashTable<std::string,LaffLayer*>     layer_info;

char* Path(std::string ipath=""); bool Add(std::string file,bool replace=false,bool hier=false,std::string rep_cell=""); bool AddCell(std::string new_cell=""); bool AddCellPointer(cell_t* new_cell=NULL); char* CellNameIterator(bool flag=false); void ResetLayerInfo(void); void BuildLayerInfo(void); bool Free(void); };

class laff_db : public Laff
{
};


Previously the laff_db was a
typedef struct laff_db
{
 char* path;
  cdmg_ht *cells;
  cdmg_ht * layer_info;
}

Doing the above lets me take baby steps in converting calls and functions from.
Laff * db.
LaffSomething(db)
db->Something();

Very good for slow conversion and testing of 17k lines of code. More before I switch to STL (string, lists, hash's)

Now the problems comes from the perl XS:

Here's my typemap :
Laff        T_PTROBJ
Laff::Node  T_PTROBJ
Laff::Cell  T_PTROBJ


Here's the top of my xs:
#ifdef __cplusplus
extern "C" {
#endif
#include <stdio.h>
#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#ifdef __cplusplus
}
#endif

#include "Ui.h"
#include "ExCommand.h"
#include "my_string.h"
#include "Laff.h"
#include "xyArray.h"
using namespace std;

typedef node_t  * Laff__Node;
typedef cell_t  * Laff__Cell;
typedef laff_db * Laff;


MODULE = Laff       PACKAGE = Laff  PREFIX=Laff

PROTOTYPES: DISABLE

int
Laff_DESTROY(db)
  Laff db
CODE:
  RETVAL = LaffFree(db);
OUTPUT:
  RETVAL

I get the following error message at compile time:

Laff.c: In function `void XS_Laff__DESTROY(PerlInterpreter*, CV*)': Laff.c:76: error: no matching function for call to `Laff::Laff(IV&)' /data/cdmg/dev/cdmg_toolbox/Laff/Laff.h:453: note: candidates are: Laff::Laff(const Laff&) /data/cdmg/dev/cdmg_toolbox/Laff/Laff.h:457: note: Laff::Laff() Laff.xs:133: error: cannot convert `Laff' to `laff_db*' for argument `1' to `int LaffFree(laff_db*)'

It seems the clash of names between my c++ class Laff and the perl-xs class Laff are in comflict. How can I resolve this?
