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