Re: [PATCH] Fix ARM64/MSVC atomic memory ordering issues on Win11 by adding explicit DMB barriers

I took a quick look at 0001.

+#ifdef _MSC_VER
+#include <intrin.h>
+#else
 #include <arm_acle.h>
 unsigned int crc;

I think you can remove this since we unconditionally do the runtime check
for MSVC.  In any case, the missing #endif seems likely to cause
problems.

Hm.  Doesn't MSVC require intrin.h?
