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