             Bug #: 53247
           Summary: [regression, c++11] can't use a function from a base
                    class of the same name in a different namespace
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: b.r.longbons@gmail.com


Created attachment 27318
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27318
testcase

With gcc 4.7 and -std=c++11, 
the 'using' statement fails to bring in a function from the base class into the
current class. This is useful to prevent hiding.

Error message:
base.cpp:12:19: error: type ‘A’ is not a base type for type ‘A’

Workaround:
Create a new member function and explicitly call the base class function.

Versions tested:
Arch gcc (GCC) 4.7.0 20120114 (prerelease)
gcc-4.7 (Debian 4.7.0-3) 4.7.0

Fabien, is this a dup of one of the other "using" regressions?

Definitely, this is a duplicate, thanks.
