A program is currently forbidden to use keywords as macro names. This restriction should be strengthened to include all identifiers that could be used by the library as attribute-tokens (for example noreturn, which is used by header <cstdlib>) and the special identifiers introduced recently for override control (these are not currently used in the library public interface, but could potentially be used by the implementation or in future revisions of the library).

Modify 188.8.131.52.2 [macro.names] paragraph 2 as follows:
A translation unit shall not #define or #undef names lexically identical to keywords.
