+ * In various places, a size_t variable or a type cast to size_t was
+ * used to perform integer-only operations on pointers.  This failed on
+ * VMS with 64-bit pointers (CC /POINTER_SIZE = 64) because size_t is
+ * still only 32 bits.  What's needed in these cases is an integer type
+ * with the same size as a pointer, which size_t is not certain to be. 
+ * The only fix here is VMS-specific.
