175  Accoding to Douglas Gwyn <gwyn@arl.mil>:
176  "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
177  9899:1999 as initially published, the expansion was required
178  to be an integer constant of precisely matching type, which
179  is impossible to accomplish for the shorter types on most
180  platforms, because C99 provides no standard way to designate
181  an integer constant with width less than that of type int.
182  TC1 changed this to require just an integer constant
183  *expression* with *promoted* type."
184 
185  The trick used here is from Clive D W Feather.
