Another parser bug with templates

[Peter Leven <leven at lpr dot e-technik dot tu-muenchen dot de>]

I've found another parser bug.  The test case is the following:

================== file: tmpfunc.cc =====================
#include <functional>

template <class T>
void do_nothing(const T& arg) 
{
  class doit : public binary_function<T, T, bool> {
    public:
      const T& goo;
      doit(const T& old) : goo(old) {};
      bool operator()(const T& a, const T& b) { return a == b; };
  };
  doit ok(arg);
  cout << ok(arg,arg);
}
================== end file =====================

egcs result:
% g++ -v -W -Wall -g -O -c tmpfunc.cc

tmpfunc.cc:6: Please submit a full bug report to `egcs-bugs@cygnus.com'.

I get a similar result with gcc-2.8.1.  The code compiles with gcc-2.7.2.3.
It doesn't matter whether "class doit" is derived from binary_function
or not.  If the function is not a template, there is no problem, nor is
there a problem if the class is defined outside the function.

P.S.  There is a bug in the 'gcc/objc/pthreads.c' file:  it attempts to
      include the file "pcthread.h" when it should be including 
      "pthread.h"

P.P.S.  Where is this option documented (i.e., for which (class of) targets 
	is it useful, and for which targets is not)?

      --enable-haifa -- Enable the new Haifa instruction scheduler in the
      compiler; the new scheduler can significantly improve code on some
      targets.  --disable-haifa is currently the default on all platforms
      except the HPPA.
