[Omp] #pragma omp for & pointer

[James Beyer]

OpenMP API version 2.5 page page 34 states that the init expression  for 
the for loop and the loop induction variable must be integer type.  
Pointers are not integers. 
Try rewriting your loop as
int i;
for ( i = 0; i < NBR_AT_M-1; i++) {
    tempory_molecule_1[i] = 
(AtomParam)coor_mol2crys(&moleculeA[i],vect_val_p.vect,vect_val_p.cm);
}
this should allow you to use omp directives on the loop.
