[Bug target/54686] std::abs (long long) resorts to std::abs (double) if llabs is absent


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54686

--- Comment #37 from Marc Glisse <glisse at gcc dot gnu.org> 2012-10-05 16:47:33 UTC ---
I see the following in cstdlib:

namespace std
{
#if !_GLIBCXX_USE_C99_LONG_LONG_DYNAMIC
  // types
  using std::lldiv_t;


Is there a particular reason to import stuff into its own namespace?
