PS. If the Apple compiler really *does* insist on specific ivar names in 
some way, we need to
do something like -

@interface NXConstantString : NSString
{
#ifdef  PRIVATE_CONST_STRING
  union {
    unichar     *u;
    unsigned char   *c;
  } _contents;
  unsigned int  _count;
#else
  char *cString;
  unsigned int len;
#endif
}

Then define PRIVATE_CONST_STRING before including NSString.h in the file 
where NXConstantString
is actually implemented.

However, I suspect it does not insist on that at all ... and there is 
rather some problem with
include files or some other problem is confusing you.
