testcase.ii:20253: error: type 'XMLFile' is not a base type for type 'XMLFile'

I think it's a reject of valid code.

Confirmed, reduced testcase:
class XMLFile;

typedef bool (XMLFile::*ParserFunctionPtr)();

struct ParserElement
{
  ParserFunctionPtr getPreFunc() const { return preFunc; }
  ParserFunctionPtr getPostFunc() const { return postFunc; }
  ParserFunctionPtr preFunc;
  ParserFunctionPtr postFunc;
};

This has been failing since "3.5.0 20040909".
