178 | Accoding to Douglas Gwyn |

179 | "This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC |
||
180 | 9899:1999 as initially published, the expansion was required |
||
181 | to be an integer constant of precisely matching type, which |
||
182 | is impossible to accomplish for the shorter types on most |
||
183 | platforms, because C99 provides no standard way to designate |
||
184 | an integer constant with width less than that of type int. |
||
185 | TC1 changed this to require just an integer constant |
||
186 | *expression* with *promoted* type." |
||
187 | |||
188 | The trick used here is from Clive D W Feather. |
