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.
