  *Purpose:
  *   This include file contains the function declarations for
  *   commonly used library functions which either don't fit somewhere
  *   else, or, like toupper/tolower, can't be declared in the normal
  *   place (ctype.h in the case of toupper/tolower) for other reasons.
  *   [ANSI]
