Judging by the recent record of std::atomic and the investigations into std::is_pod, this is not necessarily the case. STLport's std::is_pod does not return the correct answer for classes (i.e., the use case you probably most care about). Our ability to use std::atomic from libstdc++ has been steadily reduced due to it not supporting the feature set we want; just recently, we now require libstdc++ 4.7 to use it so we can get it to work with enums. Granted, <atomic> and <type_traits> are probably the most compiler-dependent headers of the lot, but it goes to show that just because it is implemented by a standard library doesn't mean it is correctly implemented.
