  53 /* Deprecated interfaces to keep the old code working (until it is all
  54    converted to the above).  Existing code such as:

  57      deprecated_complain (&msg, addr);
  58
  59    should be replaced by either the new call (for the singular case):
  60
  61      complaint (&symtab_complaints, "msg 0x%s", paddr (addr));
  62
  63    or with a wrapper function (for the many-of case):
  64
  65      msg_complaint (CORE_ADDR addr)
  66      { complaint (&symtab_complaints, "msg 0x%s", paddr (addr)); }

  69
  70    Yes, the typo is intentional.  The motivation behind this interface
  71    change is to eliminate all possability of this problem re-occuring
  72    (it has occured in the past and no one is sure that it isn't
  73    present now).
  74
  75    Support for complaining about things in the symbol file that aren't
  76    catastrophic.
  77
  78    Each such thing gets a counter.  The first time we have the problem,
  79    during a symbol read, we report it.  At the end of symbol reading,
  80    if verbose, we report how many of each problem we had.  */
