>Description:

If i compile the source below and look at the generated code, i see
that the reference to the rcp::EntryRCPID constructor is said to be
in the global namespace, _not_ the rcp namespace.

If the typedef is removed, then the external reference moves back
to the rcp namespace.  Oddly, if the EntryRCPID class is made non-virtual
by removing the destructor declaration, and if i turn on debugging,
then the external name also moves back to the rcp namespace.

>How-To-Repeat:

---------------------------------------------------------------------
namespace rcp {

struct EntryRCPID
{
  EntryRCPID();
  virtual ~EntryRCPID();
};

typedef EntryRCPID                  EntryRCPID;

}

void xyzzy()
{
  rcp::EntryRCPID x;
}

---------------------------------------------------------------------


$ ./cc1plus -quiet x.cc
$ c++filt < x.s | grep EntryRCPID
        call    EntryRCPID::EntryRCPID()
        call    EntryRCPID::~EntryRCPID()

If i comment out the destructor declaration in the above and add -g
to the compilation, i get instead the following results:

$ ./cc1plus -g -quiet x.cc
$ c++filt  < x.s | grep EntryRCPID
        .stabs  "EntryRCPID:T(0,25)=s1operator=::(0,26)=#(0,25),(0,27)=&(0,25),(0,28)=*(0,25),(0,29)=&(0,25),(0,21);:rcp::EntryRCPID::operator=(rcp::EntryRCPID const&);2A.;__base_ctor::(0,30)=#(0,25),(0,21),(0,28),(0,29),(0,21);:rcp::EntryRCPID::EntryRCPID(rcp::EntryRCPID const&);2A.;__comp_ctor::(0,30):rcp::EntryRCPID::EntryRCPID(rcp::EntryRCPID const&);2A.;__base_ctor::(0,31)=#(0,25),(0,21),(0,28),(0,21);:rcp::EntryRCPID::EntryRCPID();2A.;__comp_ctor::(0,31):rcp::EntryRCPID::EntryRCPID();2A.;;",128,0,0,0
        .stabs  "EntryRCPID:Tt(0,25)",128,0,4,0
        call    rcp::EntryRCPID::EntryRCPID()
