181     Accoding to Douglas Gwyn <gwyn@arl.mil>:
182 	"This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
183 	9899:1999 as initially published, the expansion was required
184 	to be an integer constant of precisely matching type, which
185 	is impossible to accomplish for the shorter types on most
186 	platforms, because C99 provides no standard way to designate
187 	an integer constant with width less than that of type int.
188 	TC1 changed this to require just an integer constant
189 	*expression* with *promoted* type."
190 
191 	The trick used here is from Clive D W Feather.
