------- Comment #5 from janis at gcc dot gnu dot org  2005-11-05 01:00 -------
I tried out a few cross compilers for i686-pc-cygwin over the last few
months.  The code compiled cleanly on 20040607.  Sometime between then
and 20040709 it started failing with a different ICE from what it gets now.
For awhile (at least from 20040921-20051127) it got only:

C:/rah/Vc/CppLib/RefCntUtil.h:119: error: declaration of
`RefCntUtil::ucPtr<T>::operator T*() const'
C:/rah/Vc/CppLib/RefCntUtil.h:101: error: conflicts with previous declaration
`RefCntUtil::ucPtr<T>::operator X*() const'

That error went away.  The current ICE and several of the other errors started
sometime between 20050227-20050404.  Here's a testcase for one of them:

class CloneableObject
{
  friend class CloneWalker;
public:
  virtual void WalkClone(CloneWalker&) const = 0;
};

class CloneWalker
{
  CloneWalker(int) {}
  CloneWalker(void) {}
};

It fails on powerpc-linux with "error: ‘CloneWalker’ has not been declared",
the first error that the large testcase gets, not the one that leads to
the ICE.
