I wonder if you are confusing TR1 (which came out several years ago), and C++11.
TR1 was designed to not need compiler extensions (although some parts of type_traits, that AFAIK no-one ever used in the TR1 days, could be improved with compiler support). TR1 added regex and tuple among others. It certainly didn't have rvalue references.
C++11 is the new big standard, which certainly requires large amounts of compiler support.

No, but I suspect the author of TFA is/has. That would explain the inconsistencies throughout his post.
