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