 155     Accoding to Douglas Gwyn <gwyn@arl.mil>:
 156         "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
 157         9899:1999 as initially published, the expansion was required
 158         to be an integer constant of precisely matching type, which
 159         is impossible to accomplish for the shorter types on most
 160         platforms, because C99 provides no standard way to designate
 161         an integer constant with width less than that of type int.
 162         TC1 changed this to require just an integer constant
 163         *expression* with *promoted* type."
 164
 165         The trick used here is from Clive D W Feather.
