--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Even without concepts we have a duplicated error message:
struct S {
template<int>
virtual int foo(int) = 0;
};
We once warn for the virtual and then again for the = 0 part.
GCC 4.1.2 just to produce just:
<source>:3: error: invalid use of 'virtual' in template declaration of 'virtual
int S::foo(int)'
While GCC 4.4 and above produce:
<source>:3: error: templates may not be 'virtual'
<source>:3: error: templates may not be 'virtual'
So this is a regression even for the C++98 case.
