             Bug #: 50371
           Summary: [C++0x] std::nullptr_t rejected as non-type
                    template-parameter
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: daniel.krueg...@googlemail.com
                CC: ja...@redhat.com


This is a placeholder entry to add support for std::nullptr_t as non-type
template-parameter (14.1 p4).

gcc 4.7.0 20110903 (experimental) in C++0x mode rejects the following code:

template<decltype(nullptr)>
struct nt;

"error: 'std::nullptr_t' is not a valid type for a template constant parameter"

The code should be accepted.
