 179
 180     According 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.
