--- Comment #1 from kinke@gmx.net ---
The `const` in the D signature doesn't apply to the reference itself, but to the type, i.e., is the same as `ref const(int[291][6])`, and as such your C++ example isn't an analogon.

Proper analogon with a 1D array, showing that the problem goes somewhat deeper:

C++:          short test27(const int (&)[291]);
Win64 mangle: ?test27@@YAFAEAY0BCD@$$CBH@Z

D:            extern(C++) short test27(const ref int[291])
Win64 mangle: ?test27@@YAFAEBY0BCD@H@Z

Related issue for Linux x64:

C++: short test27(const int (&)[6][291])
     _Z6test27RA6_A291_Ki

D:   extern(C++) short test27(ref const int[291][6])
     _Z6test27RKA6_KA291_Ki

Note that the C++ mangling of `const(int[291][6])` and `const(int)[291][6]` is
identical for both MSVC and Itanium (and that's fine IMO).
