CORBA24 — #pragma version issue

In the CORBA 2.4 spec, chapter 10, the definition of #pragma ID has
been modified so that later re-declarations of the same ID for a type
are permitted. Before, it was explicitly an error to use #pragma ID
for a type more than once, even if the same IDs were given.

The section of #pragma version has not been updated. This means that
handling of the two similar pragmas is now inconsistent:

interface A {};
#pragma ID A "LOCAL:foo"
#pragma ID A "LOCAL:foo" // OK in 2.4, error in 2.3

interface B {};
#pragma version B 3.4
#pragma version B 3.4 // Error in 2.4 and 2.3

Should #pragma version be updated to be consistent with #pragma ID?
