I have two straightforward questions. The first one is :

1- Do anyone has a class (whatever name) that allows to declare
   multidimensional arrays, where the index for each dimension 
   is of a particular (possibly different) type. Eg. something like:

   double a[int 5][double 6][enum c];

   that allows to initialize a matrix a , where the first index is 
   an integer in the range 1-5 (int) , the second index is in the 
   range 0-6 (double), and the third in the range of the (enum c).

	may be the indexes have to be of types that can be enumerated...

    The operations could be :

	a[2][3.0][c1] = 3.0;
	b = a[4][3.0][c2];

     I have only made this example for onne index. I think that to do in
     a number of indexes that is bigger than 1 (annd that can be arbitrary)
     looks pretty difficult...

     May be there is not such a solution... If someone finds one, can you
     mail me yours. Tx, Alberto

 2- The second question is easier. Is the latest version of g++ (i.e.
    I think g++-39) compatible with version 2.0 of AT&T?
    If nnot , do you know the main differences,. Tx again...
