Users are allowed to say
#define turn_on 1
#include <vector>

It looks like this would cause an error if profiled.

That seems problematic to me - does it mean that users wanting to
improve their use of standard containers must use (and possibly write)
non-standard containers?

Would it be possible to expose the standard containers via a different
namespace, so they can be used to gather statistics?

e.g.__gnucxx_not_profiled::vector would be a std::vector-compatible
type (based on the same code) without profiling support, that could be
used to gather statistics about std::vector use - is that possible, or
have I misunderstood what you meant?

Just my two (not a libstdc++ maintainer) cents,
