<pre>GCC bug. The code is valid.
Apparently GCC is confused by the 'auto', and rejects the mismatch of types
'const A::B' vs 'const auto', rather than checking the types match after
deduction.
MSVC appears to have the same bug as GCC.
ICC also appears to have the same bug. It also has a bug where it doesn't allow
'constexpr' to be added in the definition.
Simpler testcase:
extern int a;
auto a = 0;
This is incorrectly rejected by MSVC and GCC. But ICC accepts this one. *shrug*</pre>
