227 Accoding to Douglas Gwyn <gwyn@arl.mil>:
228 "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
229 9899:1999 as initially published, the expansion was required
230 to be an integer constant of precisely matching type, which
231 is impossible to accomplish for the shorter types on most
232 platforms, because C99 provides no standard way to designate
233 an integer constant with width less than that of type int.
234 TC1 changed this to require just an integer constant
235 *expression* with *promoted* type."
237 The trick used here is from Clive D W Feather.
