180 Accoding to Douglas Gwyn <gwyn@arl.mil>:
181 "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
182 9899:1999 as initially published, the expansion was required
183 to be an integer constant of precisely matching type, which
184 is impossible to accomplish for the shorter types on most
185 platforms, because C99 provides no standard way to designate
186 an integer constant with width less than that of type int.
187 TC1 changed this to require just an integer constant
188 *expression* with *promoted* type."
189
190 The trick used here is from Clive D W Feather.
