  178.     Accoding to Douglas Gwyn <gwyn@arl.mil>:
  179.         "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
  180.         9899:1999 as initially published, the expansion was required
  181.         to be an integer constant of precisely matching type, which
  182.         is impossible to accomplish for the shorter types on most
  183.         platforms, because C99 provides no standard way to designate
  184.         an integer constant with width less than that of type int.
  185.         TC1 changed this to require just an integer constant
  186.         *expression* with *promoted* type."
  187.  
  188.         The trick used here is from Clive D W Feather.
