Hm, my bad. I guess I was literally just a few versions behind. It does compile
with the latest DMD. It looks like it also compiles with the latest beta
version of LDC2 as well.

There is one more __declspec issue I've come across that is still present as of
DMD v2.105.0.

Error: found `__declspec` instead of statement

This error seems to happen with the following code:

void fun() {
        __declspec(align(16)) short data[64];
}

This does not happen if the variable is in global scope or part of a struct. As
far as I've tested, it only occurs if the variable is declared inside a
function body.
