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