<pre>Clang's behavior is correct.
GCC misparsed the second parameter and somehow believes A was given only one
template argument.
MSVC and EDG/ICC are complaining that a prior function parameter was used in a
later parameter, but that can be valid (depending on the type T and what
overload resolution for operator== finds), so that error should not occur until
substitution when it should be suppressed by SFINAE.</pre>
