           Summary: tuple_cat only accepts two arguments
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jewillco@osl.iu.edu


The tuple_cat function in <tuple> (in C++0x) is documented in the FDIS as
taking any number of parameters, while the libstdc++ version accepts exactly
two.
