If I have an array of 32 bits, can I cast this to an integer?  Or do I need to
declare a union of this array
with an integer an then access the array as an integer through that?

You'll have to use a union (although I would argue for a cast version). It's pretty doggie code (well at least my version is).

union bittoarray
{
   bit [] BIT;
   int [] INT;
}

int [] convert(bit [] array)
{
   bittoarray cov;
   cov.BIT = array;
   cov.INT.length = cov.INT.length / (int.sizeof * 8);
   return cov.INT; //Note that you should no longer use the bit version
}


int main ( char [] [] args )
{
   bit [] barray;
     barray.length = 32;
   barray[2] = 1;        int [] iarray = convert(barray);

   printf("%d\n",  iarray.length);
   printf("%d\n",  iarray[0]);
}

How about
   bit[] p1;
   int[] p2;
   p1 = new bit[32];
   p1[0] = 1;
   p1[2] = 1;
   p2 = (cast(int*)p1)[0..1];
   printf("%d\n",p2[0]);
   p2[0] = 4;
   printf("%d %d\n",p1[0],p1[2]);

I stand corrected.
