GCC 4.0 pragma interface/implementation regression with templates

[Peter Soetens]

Hello,

The attached implementation/header issues a warning when

$ gcc-4.0    -c -o test_undefined.o test_undefined.cpp
undefined_constructor.hpp:13: warning: inline function 'Base::Base()' used but 
never defined

This does not happen with 3.x compilers. If you remove the
#pragma interface, the warning disapears. It does also not happen
if you write 
#pragma implementation "undefined_constructor.hpp"
in the cpp file.

It apears to be triggered when using a template class with a base class.
I had similar warnings for a missing destructor.
