           Summary: [4.7/4.8 regression] Bogus warning: 'A' has a field
                    'A::e' whose type uses the anonymous namespace
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ppluzhni...@google.com


This one is recent regression of gcc-4_7 branch.
Confirmed with current trunk r196749.


namespace {
#1 "foo.cc"
enum E { };
}

struct A
{
    enum E e;
};


g++ -c foo.ii
foo.cc:4:8: warning: ‘A’ has a field ‘A::e’ whose type uses the anonymous
namespace [enabled by default]

Deleting the '#1 "foo.cc"' line makes the warning go away.
