--- 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.

--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the reduced testcase this is what clang produces:
<source>:3:5: error: 'virtual' cannot be specified on member function templates
virtual int foo(int) = 0;
^~~~~~~~
<source>:3:17: error: illegal initializer (only variables can be initialized)
virtual int foo(int) = 0;
^
MSVC:
<source>(3): error C2898: 'int S::foo(int)': member function templates cannot
be virtual
<source>(3): error C2187: syntax error: 'constant' was unexpected here
<source>(3): note: This diagnostic occurred in the compiler generated function
'int S::foo(int)'
ICC:
<source>(3): error: "virtual" is not allowed in a function template declaration
virtual int foo(int) = 0;
^
<source>(3): error: expected a ";"
virtual int foo(int) = 0;
^
Clang's error message is incorrect even because it says only variables can be
initialized which is not true as virtual functions can be initilized to 0 so it
can be considered a pure virtual.
Maybe GCC's second error message could be changed to talk about pure virtual
and such.
