| "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. |
