Accoding to Douglas Gwyn <gwyn@arl.mil>:
|
|
"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."
