             Bug #: 53258
           Summary: Many symbols cannot lookup when loading plugin in
                    configured with --enable-build-with-cxx.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: plugins
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: flast@flast.jp


Many symbols are exported as C++ symbol that GCC configured with
--enable-build-with-cxx. Such symbols are used by plugins and will load plugin
failed.

I think it will impact to cxx-conversion branch also.

I tested only GCC 4.7.1 20120428 .
