syntax error : missing ';' before '*' compile error using diffpack library with vsc++6.0

Hi!

I am trying to use the c++ library called Diffpack. The library is only compatible with vsc6.0. When trying to compile any of the supplied applications in vsc++6. I get the following errors:
spacetimescale.h(187) : error C2143: syntax error : missing ';' before '*'
spacetimescale.h(187) : error C2501: 'Vec_NUMT' : missing storage-class or type specifiers
spacetimescale.h(187) : error C2501: 'a_parameter' : missing storage-class or type
Here is some code sample from the file

class ScalarScale : public HandleId
//-----------------------------------------------------------------------------
{
  Vec(NUMT)* a_parameter;  // array to be scaled
  NUMT*      n_parameter;  // number variable to be scaled
  Ptv(NUMT)* p_parameter;  // point vector to be scaled
  // only a_parameter, n_parameter _or_ p_parameter can be used
  // two of them must be NULL, the one that is not NULL is the one to be used
  // the settings of a_parameter, n_parameter etc is performed in the
  // attach functions

public:
  String quantity_name;  // name of scalar quantity to be scaled
  NUMT scale_factor;     // scaled_value = factor * (old_value - reference)
  NUMT scale_reference;
  bool is_scaled;     // indicator reflecting calls to scale/unscale

  ScalarScale (const char* quantity_name = NULL);
 ~ScalarScale ();

Another strange thing is that the header files that are in the same directory as the application is includede with <>, not " ". So I have to manually change this.
Some sample code from wawe1.cpp:

#include <ElmMatVec.h>
#include <readOrMakeGrid.h>
#include <SparseDS.h>
#include "Wave0.h"

Wave0:: Wave0 () {}
Wave0::~Wave0 () {}

void Wave0:: adm (MenuSystem& menu)
{
  SimCase::attach (menu); 
  define (menu);  menu.prompt();  scan();
}

void Wave0:: define (MenuSystem& menu, int level)
{
  menu.addItem (level, "time parameters", "TimePrm::scan syntax",
                "dt=0.05, t in [0,0.9]");
  menu.addItem (level, "gridfile",
                "filename or P=Prepro.../geometry/partition",
                "P=PreproBox | d=1 [0,1] | d=1 elm_tp=ElmTensorProd1 "
  "div=[10], grading=[1]");
  menu.addItem (level, "wave velocity", "c", "1.0");
  menu.addItem (level, "sigma",
  "steepness parameter in initial condition", "1000.0");
  SaveSimRes:: defineStatic (menu, level+1);
  FEM:: defineStatic (menu, level+1);
}



Any help is appreciated
