[Bug c++/29356] New: typedef name denoting unnamed class should have external linkage

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In this code:

typedef class
{
public:
  void m();
} C;

void
C::m()
{
}

void
f()
{
  C c;
  c.m();
}

// { dg-final { scan-assembler "(.globl|.global)\[ \t]+[_]+ZN1C1mEv" } }

C is a typedef name which accroding to 7.1.3 is used to denote the unnamed
class.  3.5 ; 4, 3rd item, specifies that this name has external linkage.
Hence, 3.5 ; 5 specifies that C::m ( __ZN1C1mEv) should have external linkage.
However, gcc fails to emit the .global directive for this symbol.
