227    Accoding to Douglas Gwyn <gwyn@arl.mil>:
228	"This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
229	9899:1999 as initially published, the expansion was required
230	to be an integer constant of precisely matching type, which
231	is impossible to accomplish for the shorter types on most
232	platforms, because C99 provides no standard way to designate
233	an integer constant with width less than that of type int.
234	TC1 changed this to require just an integer constant
235	*expression* with *promoted* type."
236
237	The trick used here is from Clive D W Feather.
