             Bug #: 14958
           Summary: Namespaces and extern "C" can result in difficult to
                    find conflicts
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: rafael.espindola at gmail.com
        ReportedBy: joerg at NetBSD.org
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Test case:

namespace js
{
  extern int ObjectClass;
}
extern "C" namespace js
{
}
int
js::ObjectClass;

I'm not sure if this is correct, but it was accepted by GCC and earlier Clang
versions. At the very least, a note pointing to the ``extern "C"'' should be
added.
