--- Comment #2 from Phil Miller <unmobile at gmail dot com> --- I just went to look at this in more detail, and I'm not sure how to interpret what I've found. If the DR in question in 225 (http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_closed.html#225), following from 197, that seems to suggest that the other compilers *shouldn't* be be treating int as if it were associated with the global namespace, since the standards committee said the lack of associated namespace is Not A Defect. Does the committee need another nudge on this point, as practice has shifted? As a user, I'd much prefer if fundamental types were not special-cased in this setting, with the standard blessing what Clang, IBM, Intel, and PGI have done, and GCC, Microsoft, and Cray adopting that approach.
