Assertion failures in mruby-pack on big endian

The good news is mruby 2.0.0 works on OpenBSD/sparc64 (previous versions failed to build). However, running the tests shows the following failures:

These failures do not occur on OpenBSD/amd64, and the test output leads me to believe this may be a general mruby-pack issue on big endian systems.

Do you have MRB_ENDIAN_BIG defined?

I'm guessing it isn't explicitly defined. I'm going to close this now, and if there are still assertion failures with it defined, I'll reopen.

I just wanted to confirm that defining MRB_ENDIAN_BIG did fix the problem. We ended up doing something similar to this so the same code works on both big endian and little endian:

 /* define on big endian machines; used by MRB_NAN_BOXING */
-//#define MRB_ENDIAN_BIG
+#include <endian.h>
+#if (BYTE_ORDER == BIG_ENDIAN)
+#define MRB_ENDIAN_BIG
+#endif
