| 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. | |
