           Summary: Template base class members are inaccessible
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: pgonzalez at bluel dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: arm-arm-elf

The attached code compiles without problems on GCC 3.3.
On gcc-3.4-20030730, it produces the following errors:

  test.cpp: In member function `void TDynArrayBase<T>::alloc(int)':
  test.cpp:18: error: `count' undeclared (first use this function)
  test.cpp:18: error: (Each undeclared identifier is reported only once for 
each 
     function it appears in.)
  test.cpp: In member function `bool TDynArrayBase<T>::isEmpty() const':
  test.cpp:25: error: there are no arguments to `getCount' that depend on a 
     template parameter, so a declaration of `getCount' must be available
  test.cpp:25: error: (if you use `-fpermissive', G++ will accept your code, 
but 
     allowing the use of an undeclared name is deprecated)

The errors go away if you remove the "#define OLD_GCC" line.
