Que ficheros de cabecera usa Connection.c ?

Puedes copiar Connection.c aqui ?

include "extend.h"

include "Item.api"

if !defined( HARBOUR )

#include <stdio.h>
typedef void * ERRORP;

endif

include "FileSys.api"

if defined( HARBOUR )

include "HbUnDoc.api"

#if !defined( __XHARBOUR__ )
    #define HB_VM_STACK hb_stack
#endif

#define _eval ( &HB_VM_STACK.Return )

else

#include "C3UnDoc.api"

endif

void DimeC( char * );
void DimeN( long );

char * _MyClType( int );
unsigned long MyFileLength( FHANDLE );
void _MyCToCl( char *, unsigned long );
void _MyDToCl( char * );

Prueba a cambiar estas dos líneas:

include "extend.h"

include "Item.api"

por:

include <hbapi.h>

copia aqui el contenido de "HbUnDoc.api"
