Proposed resolution:

Append a new sentence to [syserr.errcat.objects]/1, and append the same sentence to 19.5.1.5/3.

All calls of this function return references to the same object.

[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]

Addresses GB-76

The C++0x FCD recommends, in a note (see 19.5.1.1/1), that users create a single error_category object for each user defined error category and specifies error_category equality comparsions based on equality of addresses (19.5.1.3). The Draft apparently ignores this when specifying standard error category objects in section 19.5.1.5, by allowing the generic_category() and system_category() functions to return distinct objects for each invocation.
